Question: In Exercises 7176, write each system in the form AX = B. Then solve the system by entering A and B into your graphing utility

In Exercises 71–76, write each system in the form AX = B. Then solve the system by entering A and B into your graphing utility and computing A^-1 B. w + x + y + z = 4 w + 3x

w + x + y + z = 4 w + 3x - 2y + 2z = 7 2w + 2x + y + z = W 3 x + 2y + 3z = 5
