Question 607604
<pre>
There are lots of different ways to solve a system of three 
equations  in three unknowns.  Post again stating which of 
the many methods for solving them which you are studying.  
Instead of just picking one and guessing that it might be 
the method you are studying, I'll just give the solution.

(x,y,z) = (3,1,2)
