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

Answer 1

To find the value of x in the equation –12 + 4x = –20, we need to isolate x on one side of the equation.

Step 1: Begin by getting rid of the -12 on the left side of the equation. To do this, we can add 12 to both sides:
–12 + 12 + 4x = –20 + 12
4x = –8

Step 2: Now we can solve for x by dividing both sides of the equation by 4:
(4x) / 4 = (-8) / 4
x = -2

Therefore, x = -2.
