Mathcad Prime 2.0 - 3 Equations - 3 Unknowns

Assuming this is a purely numerical problem, the Given-Find or Given-Minerr should work.

For a quick answer I would solve numerically using the minerr function as suggested.

If you need a symbolic answer first simplify the equation for phi. Symbolic solvers don't like absolute functions. Solve for the positive case and then the negative case. I will try this problem later on tonight. BTW, I use Mathcad 13 and wxMaxima.

I use Given = Find for symbolic solutions too not just numerical ones.
I solve a lot of system of equations but most are simple polynomials. My gut tells me the symbolic answer is going to be mess.

The problem can be solved symbolically, too, and the result isn't that clumsy ar all.
Don't have a Prime installed here (and if, it would be P3) so here is a screenshot of the solution in Mathcad 15 (still the better version anyway).
