Find A and B if, `A+B=[[1,5],[7,3]]` and `A-B=[[11,9],[7,1]]`.

If A=[[1,3,5],[-2,5,7]] and 2A-3B=[[4,5,-9],[1,2,3]], find B

If A+B=[[2,4],[3,5]] and A-B=[[8,6],[7,1]] . Then find A and B.

If A-2B=[[-7,7] , [4,-8]] and A-3B= [[-11,9] , [4, -13]] then find the matrices A and B

1. (a) If A=[[2,7],[9,8]]" and "B=[[1,2],[0,3]], then find (A-B)

If A = {5, 7, 8} and B = {9, 11}, then

Verify (AB)^(-1)=B^(-1)A^(-1) for the matrices A and B where A=[{:(3,7),(2,5):}] and B=[{:(6,8),(7,9):}]

Verify (AB)^(-1)=B^(-1)A^(-1) for the matrices A and B where A=[{:(3,2),(7,5):}] and B=[{:(6,7),(8,9):}]

If A=[[3,9,0],[1,8,-2]] and B=[[4,0,2],[7,1,4]] ,find A+B and A-B .

If A=[[-1,2,3],[5,7,9],[-2,1,1]] and B=[[-4,1,-5],[1,2,0],[1,3,1]] , then verify that (i) (A+B)'=A'+B' (ii) (A-B)'=A'-B'

Find matrices A and B, if A+B=[{:(1,0," "2),(5,4,-6),(7,3," "8):}]" and "A-B=[{:(-5,-4,8),(11," "2,0),(-1," "7,4):}].
