#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#
