linear system using Gauss-Jordan elimination. The basic observation is that for a linear system with augmented matrix A we have following relationships between the number of solutions of the system and rref(A). (1) If there is a pivot in the nal column of A (i.e., in the constant column), then the system is inconsistent, i.e., there is no solution.
