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
