Use the Gauss-Jordan method to solve the system of equations. If the system has infinitely many solutions, let the last variable be the arbitrary variable.x + 3y - 2z - w = 104x + y + z + 2w = 10-3x - y - 3z - 2w = -7 x - y - 3z - 2w = -3

A. {(0, 5, -5, 4)}
B. {(1 + w, 3 - 2w, -1 + 2w, w)}
C. {(10, 10, -7, -3)}
D. {(1, 3, -1, 2)}
