Can Mathematica solve PDE's other than the Wave equation?  I thought that
it can solve initial value PDEs.  Also, I think that the documentation
states that Mathematica can solve systems of PDE's.  Can someone tell me
why mathematica can't solve the following equations?  I may have posed the
problem incorrectly to mathematica.  I basically had to write a C++ program
to do the job.

dX/dz = Q-X 
dQ/dt = X-Q

BC: 	X=1 @z=0 for all t
	Q=0 @t=0 for all z
	Both derivatives are partial dervatives

Can mathematica solve this system of PDE's?
