Solve Math Relation for V in Terms of Z and A

[msimard8]

Homework Statement

I need to express V in terms of Z and A.

i know

V= (3/5)Y + (2/5)Z

given

y=2A-3X
X=(1/6)Z + (5/6)Y

Homework Equations

The Attempt at a Solution

ok. my first attempt was to isolate y in the second equation, and let the two equations equal each other. That eliminates y so i can't solve the problem. I don't think

i need a hint to start at least

thanks

A simple hint: you need to express Y in terms of Z and A from the second and third equation, and then return to the first one. (i.e. eliminate X)
