Your functions are pretty gnarly so you might consider using wolframscript which is a command line version of Mathematica. The first reason is one of practicality sure we can solve a system of nonlinear algebraic equations using the multivariate Newton Raphson Method, but, for a system of n equations, we have to first analytically evaluate the functional form of n2partial derivatives. You'll need to compute the partial derivatives of your functions to be able to compute the Jacobian matrix and then need to invert it. If you wanted to work it out on your own then check out this link: You could use either scipy or mpmath, check out this answer Find roots of a system of equations to an arbitrary decimal precision Sorry for my bad English and thank you for your help! On the internet I find a lot of examples but they use easier system of equation as is mine.

I want to use Newton-Raphson method, but I do not know how. These two equation needs to be equal to 0 or very close to 0.
