A Solver for Systems of Linear Equations in Excel

This is a linear system of equations solver in Excel.

The size of the system is programmable by the user from 2 to 20 which means, depending on the setting selection, the model can instantly find the solution of linear systems starting from 2 equations and 2 unknowns up to 20 equations and 20 unknowns.

It uses the following built-in Excel spreadsheet functions: MMULT(), MINVERSE() and TRANSPOSE().

Like everything on this site, the model is fully open, so you can see how it’s made.
