Which value is x in this solution of the equation: –12 + 4x = –20? (Show all of your steps)

Answer 1

To solve the equation –12 + 4x = –20, we need to isolate x.

First, let's get rid of the -12 by adding 12 to both sides of the equation:

–12 + 4x + 12 = –20 + 12
4x = –8

Next, let's isolate x by dividing both sides of the equation by 4:

4x/4 = -8/4
x = -2

Therefore, x is equal to -2.
