Question

By using
Cramer's method 2x-y+3z=8 , -x+2y+z=4, 3x+y-4z=0​

Answer 1

Answer the following questions for 3 times 3 matrices A and B If |A| = 3, then [A^-5] If |A| = -2, then [A^T] = If |A| = 2, and [B] = 3, then [AB]^-1 = Find the minor M_12 and cofactor C_12 of the following matrix A = [0 2 1 3 -1 2 4 3 1] Use Cramer's rule to solve the following system of linear equations for y. -x+ 2y- 3z = 1 2x + z = 0 3x- 4y+ 4z = 2
