help needed immediatly before tommorrow:
(a) Write down the augmented matrix corresponding to the linear system:
4x1 + 2x2 − 7x3 − 11x4 = 5
2x1 + 1x2 − 2x3 − 4x4 = 2
4x1 + 2x2 − 10x3 − 14x4 = 6
(b) Use Gauss-Jordan elimination to reduce this matrix to reduced row-echelon form.
(c) Solve the linear system.
