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

Jan 30, 2018

$x = 14$

#### 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.

$- 2 x - 13 = - x - 27$

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

$- x - 13 + 13 = - 27 + 13$

$- x = - 14$

$\frac{- x}{-} 1 = \frac{- 14}{-} 1$

$x = 14$

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.

$- 2 \left(14\right) - 13 = - \left(14\right) - 27$

$- 28 - 13 = - 14 - 27$

$- 31 = - 31$
