Dear Sirs,

	When I want to eliminate a variable of a system of DEQ, I can't
eliminate its derivatives:


Eliminate[{a y[z]-b s'[z]==0,d s[z]+f y'[z]+g s'[z]+h 


d s[z]== -g s'[z]-f y'[z]-h s''[z]

depends on y'[z] when in fact it is possible to eliminate it deriving
the first equation and putting them in the second one.

I will agree any help.
