Let A be a 4 x 4 matrix, and set x = X4 We know that the general solution of the linear system Ax = b is: X1 X2 X3 X1 = −3x₂ + x4 - 3 : free = -2x₁- // : free X2 X3 b - 2 0 -3 9 and 0 = X4 Is the linear system Ax = 0 consistent? If your answer is "Yes", you should write down the general solution of the system Ax = 0.
