Answer:

Value of z = 7

Value of y = 30

Step-by-step explanation:

We are given the following equations in the question:

$y = 9 + 3z\\y = 65 -5z$

We have to solve the given equation for y and z.

Equating the two equations we get,

$y = 9 + 3z\\y = 65 -5z\\9 + 3z = 65-5z\\3z + 5z = 65-9\\8z = 56\\\\z = 7\\y = 9+3(7) = 30$

Value of z = 7

Value of y = 30
