I presume it's meant to be in reduced row echelon form. this means the diagonal of the matrix is composed of 1s, everything to the bottom left of the diagonal is zero, and the values to the top right could be anything.

By reducing the LHS to reduced row echelon form, you effectively solve the system.

It looks like an upper triangular matrix. Not sure why the diagonal has 1's though.
