Understanding the Equation and Order of Operations

Alright, before we jump into solving for x, let's take a moment to understand what we're dealing with. The equation 3(x-1)-(4x-5)=2(5x-1)-7 is a linear equation. What does that mean? Well, it simply means that the highest power of the variable x is 1. No x squared, no x cubed – just plain old x. These types of equations are generally straightforward to solve, and the goal is always the same: to isolate x on one side of the equation. But before we get to the isolation part, we need to understand the order of operations. This is where the acronym PEMDAS or BODMAS comes in handy. Remember those? Parentheses/Brackets, Exponents/Orders, Multiplication/Division (from left to right), Addition/Subtraction (from left to right). This order is crucial. It dictates the sequence in which we perform operations to simplify an equation. By following PEMDAS/BODMAS, we ensure that we're doing the operations in the correct order, leading us to the correct solution. Remember that the order of operations is crucial for arriving at the correct answer. Get this wrong, and the entire solution will be off. This might sound intimidating, but trust me, it's not that complicated, and with practice, it will become second nature. Understanding the order of operations is the foundation upon which all algebraic manipulations are built, so take your time, and make sure you're comfortable with it. Ready to move on? Let's go!

Step-by-Step Solution: Unraveling the Equation

Now, let's roll up our sleeves and solve the equation 3(x-1)-(4x-5)=2(5x-1)-7 step by step. We will break down each step so that everyone can follow along easily. Remember to take notes so you can apply this to other, similar equations. This is where the real fun begins! First, we need to get rid of those pesky parentheses. We'll do this using the distributive property, which states that a(b + c) = ab + ac. Let's apply this to our equation: Start with the left side: 3(x-1). Distribute the 3: 3 * x - 3 * 1 = 3x - 3. Now consider -(4x-5). Remember that the negative sign in front of the parentheses means we're essentially distributing a -1: -1 * 4x + -1 * -5 = -4x + 5. Putting it all together, the left side becomes 3x - 3 - 4x + 5. Then we address the right side. Distribute the 2: 2 * 5x - 2 * 1 = 10x - 2. We still have the -7 at the end, so the right side is 10x - 2 - 7. Simplifying, our equation now looks like this: 3x - 3 - 4x + 5 = 10x - 2 - 7. Isn't that better? Next, let's simplify each side by combining like terms. On the left side, we have 3x - 4x, which equals -x. We also have -3 + 5, which equals 2. So, the left side simplifies to -x + 2. On the right side, we have 10x and -2 - 7, which equals -9. So, the right side simplifies to 10x - 9. Our equation now looks much cleaner: -x + 2 = 10x - 9. Now we want to get all the x terms on one side and the constant terms on the other. Let's add x to both sides of the equation: -x + x + 2 = 10x + x - 9, which simplifies to 2 = 11x - 9. Then, add 9 to both sides: 2 + 9 = 11x - 9 + 9, which simplifies to 11 = 11x. Finally, divide both sides by 11 to isolate x: 11 / 11 = 11x / 11. This gives us 1 = x, or x = 1. Congratulations, you have solved for x! We went step-by-step to arrive at the solution. Let's recap the steps: Distribute, simplify, combine like terms, and isolate x. You've got this!

Checking Your Work: Ensuring Accuracy

Alright, so we've solved for x and found that x = 1. But how do we know if we're right? The beauty of equations is that we can always check our answer! This is an important step to ensure we haven't made any mistakes along the way. To check our answer, we substitute x = 1 back into the original equation 3(x-1)-(4x-5)=2(5x-1)-7. Wherever we see x, we replace it with 1. So, the equation becomes 3(1-1)-(4*1-5)=2(5*1-1)-7. Let's simplify each side separately. On the left side: 3(1-1) = 3(0) = 0. Then, (4*1-5) = (4-5) = -1. So, the left side is 0 - (-1) = 1. On the right side: 2(5*1-1) = 2(5-1) = 2(4) = 8. Then, 8 - 7 = 1. So, the right side is 1. We now have 1 = 1. Since both sides of the equation are equal, our solution x = 1 is correct! This process of checking your answer is crucial. It helps catch any errors you might have made during the solving process. If the left side and right side don't match after substituting your answer, it means you've made a mistake somewhere. Don't worry, it happens to the best of us. Simply go back and review your steps to find the error. Checking your work is an excellent habit to develop, as it builds confidence in your answers and reinforces your understanding of the concepts. Keep practicing, and always remember to check your solutions. The more you do it, the better you'll get at catching those pesky mistakes early on. And that's how you know you got it right! Keep up the good work!

Common Mistakes and How to Avoid Them

Solving equations is a skill, and like any skill, it improves with practice. However, there are some common pitfalls that many people encounter along the way. Knowing these common mistakes can help you avoid them and become a more proficient equation solver. One of the most common mistakes is making errors when distributing. Remember to carefully distribute the number or the negative sign to every term inside the parentheses. Another common mistake is not combining like terms correctly. Make sure you're adding and subtracting terms with the same variable and exponent. Another common mistake is forgetting to perform the same operation on both sides of the equation. Whatever you do to one side, you must do to the other to keep the equation balanced. Missing a negative sign is also a frequent mistake. Be very careful with negative signs, especially when distributing or subtracting terms. Also, sometimes people make arithmetic errors. It's easy to make a small calculation mistake, so always double-check your arithmetic, especially when dealing with negative numbers. To avoid these common mistakes, take your time, and write down each step carefully. Double-check your work at each step and remember the order of operations. Check your answer by substituting it back into the original equation. If the left side and right side are equal, your answer is correct. With practice, you'll become more aware of these pitfalls and develop strategies to avoid them. Remember, it's okay to make mistakes – it's how we learn and improve! Just keep practicing, stay organized, and always double-check your work, and you will be a pro in no time.

The more equations you solve, the more comfortable you'll become with the process. Start with simpler equations and gradually work your way up to more complex ones. Don't be afraid to try different types of equations. Second, stay organized. Write down each step clearly and neatly. This will help you keep track of your work and avoid making careless mistakes. Use separate lines for each step, and be sure to show all your work. This will also make it easier to go back and check your work if needed. Third, simplify as much as possible. Before you start isolating x, simplify both sides of the equation by combining like terms. This will make the equation easier to work with. Fourth, choose your strategy wisely. There are often multiple ways to solve an equation. Think about which approach is the most efficient and least prone to errors. Sometimes, moving all the x terms to the left side and constants to the right side is the best approach. Fifth, use visual aids. If you're a visual learner, consider using diagrams or drawings to help you understand the equation. This can be especially helpful when dealing with word problems. Sixth, break down complex problems. If you encounter a complex equation, break it down into smaller, more manageable steps. This will make the process less overwhelming. Seventh, learn from your mistakes. Don't be discouraged if you make mistakes. Instead, view them as learning opportunities. Go back and review where you went wrong, and then try solving the problem again. Eighth, seek help when needed. If you're struggling with a particular concept, don't hesitate to ask for help from your teacher, a tutor, or a classmate. There's no shame in asking for help! Finally, have fun! Solving equations can be challenging, but it can also be very rewarding. Celebrate your successes and enjoy the process of learning and mastering this valuable skill. Keep these tips and tricks in mind as you tackle equations, and you'll find that solving for x becomes easier and more enjoyable over time.
