a) find the value of x
b) state the postulate or theorem that justifies your answer

please explain how to solve this!

Answer 1

x=35

Explanation:

I put a picture of my work on paper for you.

Basically you more 70 over to the right outside of the problem making it 2x=70 because we added 70 making it positive then divide 2 from 2x giving you x and then divide 70/2 getting 35 you do this to make the equation balance out. so x=35
