I seem to recall a number of iterative methods for solving these
problems. My memory is very rusty on this (it's been about 6 years),
but you should be able to approximate values for X, Y, & Z and then run
through iterations with them. Each iteration changes the values of X,
Y, & Z slightly bringing them ever so closer to the real answers.
College text books on numerical analysis are good sources for this
stuff. An example may be at the following URL (watch for line breaks)
