I remember this system is of 3 order nonliearity. Analytic solution is possible. Generally nonlinear system needs iterative method to get numerical solution. See the book
Iterative Solution of Nonlinear Equations in Several Variables
Book by James M. Ortega

Write down the 11 eqs of the nonlinear system. Use some software, like Matlab, maple, mathematica to solve it. Hope it works.

I am not sure whether solve command can do it. Search matlab command to solve equation system. I don't have too much experience on Matlab but I know it should have command to solve this system.
