Answer 1

Answer:

Step-by-step explanation:

(2- 9z) 5 = (17 - 4z) 4

10 - 45z = 68 -16z

10-68 = 45z - 16z

-58 = 29 z

-58/29 = z

Answer 2

Step-by-step explanation:

Hey friend add my answer as brainleist one

(2 - 9z)/(17-4z)=4/5

●5(2-9z) = 4(17-4z)

●10-45z = 68-16z

●-45z + 16z = 68-10

●-29z = 58

●z = 58/-29 = -2
