Which equation can be used to solve the 2 by 2 matrix row 1, 2 6 row 2, 0 1 the 2 by 1 column matrix row 1 x sub 1 row 2 x sub 2 is equal to the 2 by 1 column matrix row 1 2 row 2 negative 3 ?

To solve Mx = b for x, multiply both sides by the inverse of M = [[2, 6], [0, 1]]. Its inverse is [[0.5, -3], [0, 1]], since their product is the identity matrix. Therefore x = [[0.5, -3], [0, 1]][[2], [-3]], which is choice C.
