There are many different methods for solving systems of equations.
I'm not going to just pick one at random and hope that's the one you're
studying. So I'll just give you the solution. If you want to know the
details on how to solve it, tell me or describe in the thank you note
what method you are studying and I'll help you. The solution is
(x,y,z) = (4,-3,2)
