Question

Solve for x.
x - 2 = 5

Answer 1

Answer: x = +7

Step-by-step explanation: In this problem, since 2 is being subtracted from x, add 2 to both sides of the equation to get x by itself.

On the left side, -2 +2 will cancel out and

on the right side, 5 + 2 simplifies to +7.

So x = +7.

Answer 2

Explanation:

x - 2 = 5

Add 2 to each side

x-2+2 = 5+2

x = 7
