Answer 6

Alright, do that and you will have something that looks like: \[A \bar v = \bar u\]So if you can find an inverse of A and left multiply both sides you will get:
\[A^{-1}A \bar u = A^{-1} \bar v\]\[I \bar u = A^{-1} \bar v\]\[\bar u = A^{-1} \bar v\]

So you'll have an equation for your vector v which has x, y, and z in it.
