Part 2 of 2 Points: 0 of 1 Write the given system as a matrix equation and solve by using the inverse coefficient matrix. Use a graphing utility to perform the necessary calculations. X1 + 19X2 + 22X3 = 42 - 6X1 + 6X2 - 20X3 = 27 10x1 - 24X2 + 30X3 = -7 . . . Find the inverse coefficient matrix. - 0.2568 - 0.9401 -0.4384 A - 0.0171 -0.1627 - 0.0959 0.0719 0.1832 0.1027 (Round to four decimal places as needed.) Solve the system. x 1 X, = X3 = (Round to the nearest tenth as needed.)
