Answer:
z = 71/29 ( = 2.45)
Step-by-step explanation:
-9(3z - 4) = -35 + 2z (by PEDMAS, expand parentheses first by distributive property)
3z(-9) - 4(-9) = -35 + 2z
-27z + 36 = -35 + 2z (add -27z to both sides)
36 = -35 + 2z + 27z
36 = -35 + 29z (add 35 to both sides and rearrange)
29z = 36 + 35
29z = 71
z = 71/29 ( = 2.45)
