If A = `[(2, 1),(1, 3)]` and B = `[(3),(-11)]`, find the matrix X such that AX = B.
Given A = `[(2, -1),(2, 0)]`, B = `[(-3, 2),(4, 0)]` and C = `[(1, 0),(0, 2)]`, find the matrix X such that : A + X = 2B + C.
Find the value of x, given that A2 = B,
A = `[(2, 12),(0, 1)]` and B = `[(4, x),(0, 1)]`
If A = `|(1215),(1117)|` and B = `|(2,7),(4,9)|` find A - 2B
