How do you solve #-2x - 13= - x - 27#?

Answer 1

#x=14#

The first thing to realize is that you have to place a value on the other side if you place another value on the other side.

#-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#

Answer 2

To solve the equation -2x - 13 = -x - 27, first add x to both sides to isolate the variable. Then, add 13 to both sides to further isolate the variable. Finally, divide both sides by the coefficient of x to solve for x.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
