Thanks for the explanation. That's a really nice introduction to getting a Groebner basis in Maple. It does result in more complicated expressions, but you're right it eliminates variables. 

Also, I like the "map(lhs-rhs,sys)" trick: it's elegant and compact. I actually wrote a proc to do that...

Thanks, that's a useful function. In my case however, the side relations are actually in the system of equations themselves, so "eliminate" is probably a more general way to do the model reduction.

Very nice! Somehow I was expecting a more complicated answer, requiring the use of Groebner bases. I did not think to look for an "eliminate" function ... I was looking through the documentation for a "reduce" or "subs" function. This does what I want. Thank you.

Thank you so much -- that was a brilliant and unexpected solution (yes, I do have Maple 13). I was not aware of the elementwise operator, and even if I were, I'm not sure if I would have used it in this context. It works beautifully. 

Thanks again!

Thanks for a most helpful answer!

That piece of code not only did what I wanted, it also taught me a few things about Maple that I did not know about. Thanks again.

Thanks for the answer. No, I'm not taking any courses -- I apologize if I missed the solution posted earlier. The trouble with these sorts of questions is that one doesn't quite know what keywords to search for. I actually did quite a bit of googling before throwing in the towel.
