-4x - 12 = 8

     + 12  +12

<u>-4x </u>=<u> 20</u>

-4     -4

<em>x = -5</em>

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.

-4x-12=8
Add12 to both sides
-4x= 20
Divide both sides by -4
X= -5
