Please attach your worksheet, rather than a picture. (You don't show what P1M or n is...)

If you want to work symbolically, then work symbolically. Something like:

Success!

What you try does not work in Prime (and also not in real Mathcad, at least not in MC15).

But there sure are a couple of workarounds which also avoid to use copy and paste.

Symbolic "solve" comes to mind:

or you define your "equations" as functions dependent on the variables you'd like to solve for to make the numeric processor happy and use the solve block without symbolics:
