x=−5

Answer 2

x=-5

Explanation:

When finding x, we basically have to isolate the variable. By isolating the variable, usually doing the opposite operation helps it.

Addition is the opposite of Subtraction

Multiplication is the opposite of Division

Let's dive into this problem!

x+7=2

(we need to isolate x. basically we need to get rid of this 7. How do we do this? since it is added by seven, we can subtract it by both sides to get rid of it on the x side.)

x+7=2

-7 -7

x=-5

(subtract 2-(-5), this adds to -5)

This is your final answer.
