Answer
y = 9
Step-by-step explanation
The question wants usto solve for y, given that
8x = 2y - z
if x = 2 and z = 2
To solve this, we just substitute the given values for x and z into the given expression to get y.
8x = 2y - z
8(2) = 2y - 2
16 = 2y - 2
We can rewrite this and have
2y - 2 = 16
Add 2 to both sides
2y - 2 + 2 = 16 + 2
2y = 18
Divide both sides by 2
(2y/2) = (18/2)
y = 9
Hope this Helps!!!
