Answer: x=15

Step-by-step explanation:

**Disclaimer** I am not quite sure of the meaning of "two-step", which I assume is the literal meaning of using two steps to solve the linear equation. If I was incorrect, you may point it out and I will redo it.

Given

x/3 - 7 = -2

Add 7 on both sides (Below is one step, I just want to make it clearer for you to understand. When you write your steps, just directly write the second part)

x/3 - 7 + 7 = -2 + 7

x/3 = 5

Multiply 3 on both sides (Below is one step, similar to the step before)

x/3 · 3 = 5 · 3

x = 15

Hope this helps!! :)

Please let me know if you have any questions

Firstly add 7 to both sides= x/3= 5
Times by 3 on both sides to get x on its own= x= 15
