    Hey , you can convert into Echelon form, and thereby finding the rank of the matrix, you can check consistency of the equations...

    find the echleon form (Gaussian) BEFORE doing row reduced echleon form (Gauss-Jordan) otherwise you will get conflicting results. Gaussian and Gauss Jordan require the same number of elementary row operations. So for example if it took 6 row operations to get to echleon (Gaussian) form, it should take 6 row operations to get to row reduced (Gauss-Jordan)
