Answer 1

First, multiply by both side by 2.
Second, subtract 9 from both sides.
What you get will be your answer :D

Answer 2

(z + 9)/2 = -3 (multiply the entire equation by 2)
z + 9 = -6 -- subtract 9 from both sides
z = -6 - 9
z = -15

check...
(z + 9)/2 = -3
(-15 + 9)/2 = -3
-6/2 = -3
-3 = -3 (correct)

answer : z = -15
