Question: Substituting and Solving Large Algebraic Expressions - Just give it time?

Hello All,

I have 6 equations that are similair in size to the one listed below. I am trying to find a single equation in terms of only 1 of the variables (s11). After finding this equation I want to solve it for that single variable. When I start plugging all these equations into eachother I get to about the last one then maple seems to get stuck evaluating. I left it on overnight thinking that if I gave it time it would eventually solve, but this didn't seem to work. My questions is, If I gave it enough time would it solve this? Is there another way to do this? Any help you guys could offer would be a great help. Thanks!
