Write the system as a matrix and solve it by Gauss-Jordan elimination. (If the system is inconsistent, enter INCONSISTENT. If the system has infinitely many solutions, show a general solution in terms of x, y, or z.)
x + 2y − z = 5
2x − y + z = 2
3x − 4y + 3z = −1
and enter your matrix. It will show you all the steps involved.
