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

If A=[[2,5],[3,7]] and B=[[1,3],[4,8]] ,then find AB.

If A+B^T=[(1,3),(4,5)] and A^T-B=[(7,8),(-1,3)] , then find matrices A and B.

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

If A and B are two matrices such that A + B = [{:(3, 8),(11, 6):}] " and " A-B = [{:(5, 2),(-3, -6):}] , then find the matrices A and B.

If A=[[2,3],[4,7]] and B=[[1,3],[4,6]] find 3A-2B

If A=[[2,3],[4,7]] and B=[[1,3],[4,6]] find 3A-2B

If A=[[2,-13,2]] and B=[[0,4-1,7]] then find the value of 3A^(2)-2B

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

If A = ({:(9, -7), (-4, 3):}) " and B"=({:(-3, -7),(-4, -9):}) , then find AB and hence find A^(-1) .
