Here is a link to an Excel file that contains the source code for the functions "solve_rd_system" (that solves the system $A x = b$, where $A$ is $ m \times n$), and the function "intersect_three_quadrics" which solves a system of three quadratic equations in three unknowns, and also other functions that solve a system of two quadratic equations in two unknowns. These are included in this file as macros (VBA script). Click on the link, to open the online file, then click on "Editing" and choose "Open in Desktop App". This will open the file in your desktop Excel program. Click "View" then select "Macros".
