Answer: D

Step-by-step explanation:

12 = [tex]\frac{2 + z}{-6}[/tex]

(-6)12 = [tex](-6)\frac{2 + z}{-6}[/tex]

-72 = 2 + z

 -2  -2

Answer:

D

Step-by-step explanation:

Multiply both sides by - 6

12*-6 = [-6 (2 + z) / - 6 ]      Cancel the - 6 s on the right.

- 72 = (2 + z)                       Remove the brackets and switch

z + 2 = - 72                         Subtract 2 from both sides

z +2 - 2 = -72 -2

z = - 74
