Question

How do you solve 9x-7= -7 for 2 step equations?

Answer 1

You add +7 to both sides and then divide by 9 to get the x alone.

Answer 2

Step 1: Add 7 to both sides of the equation.
9x - 7 = -7 
     +7    +7  
9x = 0
Step 2: Divide both sides by 9.
9x/9 = 0/9x = 0
Therefore, your answer is x = 0
