Can't bring Maxima to resolve reverse of a function

Thanks to all who replied.

Yes, it's just big and tedious and I want to anlyse the formula by
various sets of the unknown, hence I liked the idea of algebra
computer support.

I wonder what the threshold is, what kind of transformations do I need
to apply until Maxima can continue to work on the formulas? I'll
experiment some more.

Thank you
