x=-14

Explanation:

(-(2x + 4))/8 = 3

((-(2x + 4))/8) * 8= 3 *8

-(2x+4) = 24

-2x -4 = 24
-2x -4 +4 = 24+4
-2x = 28
(-2x)/-2 = 28/-2
x= -14

x = -14

Explanation:

Step 1) Multiple each side of the equation by 8 to eliminate the fraction.
Step 2) Multiple the term in parenthesis by -1 to remove the parenthesis
Step 3) Solve for x while keeping the equation balanced

8((-(2x + 4))/8) = 3*8

-(2x + 4) = 24

-2x - 4 = 24

-2x - 4 + 4 = 24 + 4

-2x - 0 = 28

-2x = 28

-2(x/-2) = 28/-2

1x = -14

x = -14
