Given matrix M 7 8 7 4 7 6 9 5 2 with M1 1197 16 19 1 62 4

Given matrix M = (-7 -8 7 4 -7 6 -9 -5 2) with M^-1 = 1/-197 (16 -19 1 -62 49 70 -83 37 81), solve the vector equation M(x_1 x_2 x_3) = (-4 -11 -16).

Solution

Dear Student Thank you for using Chegg !! x1 -4 x2 = M^-1 * -11 x3 -16 M^-1 = 1/(-197) * 16 -19 1 -62 49 70 -83 37 81 x1 16 -19 1 -4 x2 = 1/(-197) * -62 49 70 * -11 x3 -83 37 81 -16 x1 * 129 x2 = 1/(-197) -1411 x3 -1371 x1 -0.65482 x2 = 7.162437 x3 6.959391 Solution
