What is the first step to solve x - 12 = 28?
Add 12 to both sides.
What is the first step to solve 3x = 15?
Divide both sides by 3.
What is the first step to solve x/4 = 12
Multiply both sides by 4.
Is x = 34 a solution for x/8 = 4?
No, 34/8 ≠ 4
What is the first step to solve x + 15 = 19?
Subtract 15 from both sides.
