Don't quite understand what your issue is with PEQUM.
I just looked at it for the first time in about a year or two. I installed the latest version. I made an equation called TEST that had the equation A^2+B+C=D.
When I solved it, it first popped up the equation in case any changes are needed, then brought up a solver where I could solve for A, B C or D.
When you exit, it asks if you want to leave the stack values or not.
If you leave them, they are sitting there labeled on the stack. If you don't, then you just open the EQUAT directory and all the variables are there.
If all you can solve is for X, is that because you only have X in your forumula???
That being said, the 50g may be a shotgun to kill mosquitos. It will do whatever you need, but it is very difficult to learn and get comfortable with in such a short amount of time. I'd recommend taking a look at the new quickstart guide which I made a few years back. It should help quite a bit I think.
