x=14

Explanation:

The first thing to understand is that if you place one value on the other side you must put it on the other side as well.

-2x - 13 = -x - 27

-2x + x - 13 = -x + x - 27

-x - 13 + 13 = -27 + 13

-x = -14

(-x)/-1 = (-14)/-1

x = 14

The last thing you can do is check if you have the correct answer. The way to do this is to substitute the value you got for x into the original equation. If both sides are equal then you have the right answer, if not go back and find your mistake.

-2(14) - 13 = -(14) - 27

-28 - 13 = -14 - 27

-31 = -31
