-4x - 12 = 8

     + 12  +12

-4x = 20

-4     -4

x = -5

To ensure that x equals -5, let's substitute the negative integer with x.

-4 x -5 - 12 = 8

-20 - 12 = 8

8 = 8

Therefore, the answer is x = -5 because we confirmed our answer by substituting x with -5 and solving the equation and got the both sides of the equation equal.
