Respuesta :

-4x + 3x = -x
-x = 2
-x/-1 2/-1
x = -2

The right answer is   x = -2

Below is first step:

First we need to pull out like factors :

 -x - 2  =   -1 • (x + 2)  

Then equation is the last part of step 1

Second step:

You need to solve a single variable equation :

2.1      Solve  :    -x-2 = 0  

Finally add  2  to both sides of the equation :  

                     -x = 2  

Multiply both sides of the equation by (-1) :  x = -2
