Step-by-step explanation:
-2x - 13 = -3x - 5
Step 1: Combine like terms
x's go with x's (-2x and -3x). To do this add 2x to both sides
(-2x + 2x) - 13 = (-3x + 2x) - 5
(0) - 13 = (-x) - 5
- 13 = -x - 5
normal numbers go with normal numbers ( -13 and -5). To do this add 5 to both sides
(- 13 + 5) = -x + (- 5 + 5)
-8 = -x + (0)
-8 = -x
Step 2: Isolate x by dividing -1 to both sides (this will take the negative sign away from the x)
![\frac{-8}{-1} =\frac{-x}{-1}](https://tex.z-dn.net/?f=%5Cfrac%7B-8%7D%7B-1%7D%20%3D%5Cfrac%7B-x%7D%7B-1%7D)
8 = x
x= 8
