The command to get a numerical solution to N polynomials with N
unknowns is NSolve. In general, Mathematica commands that return
numerical solutions start with a capital N such as NMinimize,
NIntegrate etc.

Also, while NSolve intended primarily for polynomials,
Mathematica is not limited to solving polynomial equations. And
in fact, NSolve will solve some non-polynomial equations.
