Sample Question 1: Algebra Basics

The Question: Solve for x: 3x + 5 = 14

The Solution:

Subtract 5 from both sides: 3x + 5 - 5 = 14 - 5
Simplify: 3x = 9
Divide both sides by 3: 3x / 3 = 9 / 3
Simplify: x = 3

The Explanation: We're using the basic principles of algebra to isolate x. First, we subtract 5 from both sides to get the term with x by itself. Then, we divide both sides by 3 to solve for x. Remember, whatever you do to one side of the equation, you must do to the other side to keep it balanced.

Tips and Tricks: Always check your answer by plugging it back into the original equation. In this case, 3(3) + 5 = 9 + 5 = 14, so our answer is correct!

Sample Question 2: Geometry Fun

The Question: A triangle has angles measuring 60 degrees and 80 degrees. What is the measure of the third angle?

The Solution:

Remember that the sum of angles in a triangle is always 180 degrees.
Add the given angles: 60 + 80 = 140 degrees
Subtract the sum from 180: 180 - 140 = 40 degrees

The Explanation: We used the fundamental property of triangles – the sum of their angles is 180 degrees. By adding the two known angles and subtracting from 180, we find the missing angle.

Tips and Tricks: Drawing a diagram can help visualize the problem. Label the known angles and the unknown angle. This can make it easier to see the relationships between the angles.
