comment $10$ Equations in $10$ variables
I'm voting to close this question as off-topic because it is way too localized. If this question is a suitable fit for the site, what is to prevent me from making up some other nonlinear system of $n$ variables with $n$ equations and asking that one? Unless this can be answered with a suitable method for solving such systems, I fail to see how solving this one problem will be of help to future visitors.
