I do not believe Solve uses the Assume database at all.

If Assume has any effect on Solve, it would be through simplification, but =
I
can't think of any examples of this off the top of my head.

         assume(x>0)$
         solve(abs(x)=3D2);

works, but only because abs(x) simplifies to x before solve even sees it!
