Answer
z=-$\frac{9}{2}$
Work Step by Step
Divide both sides of the equation by 8 to isolate the variable.
-36=8z
8z=-36
$\frac{8z}{8}$=-$\frac{36}{8}$
z=-$\frac{36}{8}=-\frac{36\div4}{8\div4}$
z=-$\frac{9}{2}$
Check the answer.
8(-$\frac{9}{2}$)=-36
-$\frac{8(9)}{2}$=-36
-$\frac{72}{2}$=-36
-36=-36
