Of course Mathematica won't do this - and several obvious variations on this
theme don't seem to work either (e.g., introducing a new variable z =
x/y, and attempting to solve the system for z).
So what's the easiest way to solve (systems of) equations for
nonatomic variables of this sort?
Thanks for any suggestions,
