Symbolically solve a multi-variable equation.

I need help solving for "K" in this equation, symbolically. I'm not sure how to use the solve block for this, any help would/will be appreciated.

But still, although obtained through the symbolic processor (Maple in this case of Mathcad 11),

the solution is numerical. See:

Are you sure that a symbolic solution exists? If yes, is your equation certainly correct?

Mathcad gives:

Also Wolfram Alpha has no solution.

Success!

Perhaps not. Can mathcad handle boundaries for K, if for example the following (prepared in Maple by professor).

But I do know this, as also provided for reference (not to be used in solutions, an exact answer is required).

If you're given values for GA & GB, you can solve numerically, just not symbolically:
