Given:

-(5z + 12) = 18

First Step:

Use distributive property and expand the parenthesis.

Also distribute the negative symbol

-5z + (-12) = 18

-5z - 12 = 18

Second Step:

Add 12 to both sides of the equation.

-5z - 12 + 12 = 18 + 12

-5z = 30

Third Step:

Divide both sides by -5

[tex]\begin{gathered} \frac{-5z}{-5}=\frac{30}{-5} \\ \\ z\text{ = -6} \end{gathered}[/tex]

ANSWER:

z = -6
