Answer 1

x = -7

Explanation:

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.

Add 11 to both sides:

x + (-11) = -18

x - 11 = -18

x - 11 (+11) = -18 (+11)

x = -18 + 11

Simplify. Combine like terms:

x = -18 + 11

x = -7

x = -7 is your answer.

Answer 2

We add 11 to each side to get rid of -11 so x = -18 + 11 = -7.
