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 cant solve the problem. I dont think

i need a hint to start at least

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)
