Solve the following systems by means of x = A-1b method, check your answer (X1 + 2x2 + 3x3 = -5, Zx1 - Xz + X3 = 13, 3x1 + Xz + 2x3 = 8, X1 + 2xz + 3x3-2x4 = 63, 2x1 + 3xz + X3+2x4 = 31, -X1 + Xz + 3x3+2x4 = -39, 3x1 + 2xz + X3-X4 = 50)

Step 1
In this case, we have: A = [1 2 3 0] [0 -1 1 1] [3 0 2 -2] [1 2 3 -2] X = [x1] [x2] [x3] [x4] B = [-5] [13] [8] [63] [31] [-39] [50] Show more…
