Question

A: -36
B: -12
C: -70
D: -74

Answer 1

D

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

Answer 2

Answer: D

Explanation:

12 =
`(2 + z)/(-6)`

(-6)12 =
`(-6)(2 + z)/(-6)`

-72 = 2 + z

-2 -2

-74 = z
