Mathematica has a built-in command LinearSolveA b that solves a linear system of equations given a coefficient matrix A and a vector of constants b.

The system I would like to solve is. To do this make an equation of the list of the left hand sides of the equations and the list of right hand sides as follows. NullSpace vectors spanning the null space of a matrix. If your equations involve only linear functions or polynomials then you can use NSolve to get numerical approximations to all the solutions. It is primarily for students who have very little experience or have never used Mathematica and programming before and would like to learn more of the basics for this computer algebra systemAs a friendly reminder dont forget to clear variables in use. LinearSolveFunction a function created to repeatedly solve a linear system.
