Given a = [(1,1),(-2, 0)] and B = [(2, -1),(1, 1)] Solve for Matrix X: 3a - 2x = X - 2b - ICSE Class 10 - Mathematics

Question

Given A = [(1,1),(-2, 0)] and B = [(2, -1),(1, 1)] Solve for matrix X:

3A - 2X = X - 2B

Solution

3A - 2X = X - 2B

3A + 2B = X + 2X

3X = 3A + 2B

3X = 3[(1, 1),(-2, 0)] + 2[(2, -1),(1, 1)]

3X = [(7, 1),(-4, 2)]

X = [(7/3, 1/3),(-4/3, 2/3)]

Is there an error in this question or solution?
