Gaussian elimination on a TMatrix

I have a “square” matrix, a system of 3 equations with 3 unknowns, that I’ve put into a TMatrix. Is there a ROOT method to perform Gaussian elimination on a TMatrix, so as to determine the values of the three unknowns? I understand ROOT uses Gauss-Jordan elimination to find the inverse of a matrix. Surely there’s a way to get just the solutions?

Please read tips for efficient and successful posting and posting code

May be @moneta can help you.

We have several decomposition methods in the TMatrix class for solving linear systems.
You can see here:
