# What software does Sage use to solve linear equations ?

Hi, I have been using Sage in my project mainly to solve a large list of large (hundred of unknowns) linear equations, i.e., `solve(eqts, variable)`

. However, Sage is so large that it becomes inconvenient to ask users to download Sage to use my work. I've tried to use `sympy`

but its equation solver is much slower compare to the one in Sage. So I am wondering what software that Sage uses underneath for linear equation solving ? It's probably one of those listed here http://www.sagemath.org/links-compone... but I don't know which.

Note that I want a solver that can give symbolic solution, e.g., instead of solutions such as `x = 3, y =6`

, it would say `x = v1, y = 2*v1`

. This is how I use `solve`

in Sage.
