Solving Equations: Find Missing Terms & Simplify
Hey guys! Today, we're going to break down how to solve a simple equation step-by-step. We'll focus on filling in the missing pieces and making sure we simplify everything along the way. Let's dive into the equation 2c + 10 = 16 and see how we can crack it!
Understanding the Equation
Before we jump into solving, let's quickly understand what this equation means. In the equation 2c + 10 = 16, 'c' is our unknown variable – the number we're trying to find. The equation tells us that if we multiply 'c' by 2 and then add 10, the result will be 16. Our goal is to isolate 'c' on one side of the equation to figure out its value. This involves performing operations on both sides of the equation to maintain the balance. Remember, whatever we do to one side, we must do to the other to keep the equation true. This principle of balance is the foundation of solving algebraic equations.
Let's think of it like a scale. The equals sign (=) represents the balance point. The left side (2c + 10) and the right side (16) must weigh the same. To find the value of 'c', we need to carefully remove items (numbers and operations) from the left side until only 'c' is left. Each step we take must keep the scale balanced. For example, if we remove 10 from the left side, we must also remove 10 from the right side. This is why we perform the same operation on both sides of the equation. Understanding this concept of balance makes solving equations much less intimidating and more intuitive. It's not just about following steps; it's about maintaining equilibrium.
Step 1: Subtracting 10 from Both Sides
The first step in solving for 'c' is to get rid of the + 10 on the left side. To do this, we perform the inverse operation, which is subtraction. We subtract 10 from both sides of the equation. This keeps the equation balanced and moves us closer to isolating 'c'.
Here's how it looks:
2c + 10 = 16
Subtract 10 from both sides:
2c + 10 - 10 = 16 - 10
This simplifies to:
2c = 6
So, the missing term after subtracting 10 from both sides is 6. This step is crucial because it simplifies the equation by eliminating the constant term on the side with the variable. By subtracting 10, we've effectively isolated the term containing 'c' (2c) on one side. This makes the next step, dividing to solve for 'c', much more straightforward. Remember, the goal is to peel away the layers around the variable until we have it all alone. Subtracting or adding is usually the first step in this process, as it helps to clear away constant terms that are added to or subtracted from the variable term. By understanding this fundamental principle, you'll be well-equipped to tackle more complex equations in the future.
Step 2: Dividing Both Sides by 2
Now we have 2c = 6. The next step is to isolate 'c' completely. Currently, 'c' is being multiplied by 2. To undo this multiplication, we use the inverse operation: division. We divide both sides of the equation by 2. Again, this is essential to keep the equation balanced.
Here's the breakdown:
2c = 6
Divide both sides by 2:
(2c) / 2 = 6 / 2
This simplifies to:
c = 3
So, the missing term after dividing both sides by 2 is 3. This final step gives us the solution to the equation. We've successfully isolated 'c' and found its value. Dividing both sides by the coefficient (the number multiplying the variable) is a common technique in solving equations. It's the last step in isolating the variable after we've dealt with addition or subtraction. The beauty of this method lies in its simplicity and effectiveness. By understanding the principle of inverse operations, we can systematically solve for any variable in an equation. This step is not just about getting the answer; it's about understanding the process of unwinding the equation to reveal the hidden value of the variable. With each step, we're moving closer to the truth, and in this case, the truth is that c = 3.
The Complete Solution
Let's put it all together to see the complete solution:
2c + 10 = 16
2c + 10 - 10 = 16 - 10 (Subtract 10 from both sides)
2c = 6
(2c) / 2 = 6 / 2 (Divide both sides by 2)
c = 3
Therefore, the solution to the equation is c = 3. We've successfully solved for 'c' by carefully applying inverse operations and maintaining balance in the equation. This method of solving equations is fundamental in algebra and forms the basis for more complex problem-solving. By understanding each step and the reasoning behind it, you can confidently tackle a wide range of equations. Remember, the key is to isolate the variable by undoing the operations that are performed on it. We started by subtracting 10 to undo the addition, and then we divided by 2 to undo the multiplication. This systematic approach is the hallmark of algebraic problem-solving, and it's a skill that will serve you well in mathematics and beyond.
Tips for Solving Equations
- Always perform the same operation on both sides: This keeps the equation balanced.
- Use inverse operations: Addition and subtraction are inverse operations, as are multiplication and division.
- Simplify as you go: This makes the equation easier to work with.
- Check your answer: Substitute your solution back into the original equation to make sure it works.
Solving equations is a fundamental skill in mathematics, and these tips can help you master it. Remember, the goal is always to isolate the variable. Think of it like peeling an onion – you remove one layer at a time until you get to the core. In the same way, you undo one operation at a time until you have the variable by itself. Checking your answer is also crucial. It's like proofreading an essay – it helps you catch any mistakes you might have made along the way. By following these tips and practicing regularly, you'll become more confident and proficient in solving equations. And remember, math is not about memorizing formulas; it's about understanding the process and applying it logically.
