1.If `A=[[1,2],[3,4]],B=[[3,8],[7,2]]` and `2X+A=B` then Find `X`

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

If A=[[2, 4 ],[4 ,3]],X=[[n],[1]] , B=[[8], [11]] and A X=B , then find ndot

If A=[[1,4,-1],[2,6,5]] and B=[[3,-2,-6],[2,0,-7]] , find A+B and A-B

If A={1,2,3,4,5}, B={1,2,3,6,7} and C{8}, then find (A-B) xx C .

If A=[[2,3,4],[-3,0,2]], B=[[3,-4,-5],[1,2,1]] and C=[[5,-1,2],[7,0,3]] , find the matrix X such that 2A+3B=X+C

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

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

If A=[(2,-1),(3,1)] and B=[(1,4),(7,2)] , find 3A-2Bdot

If A={1,2,3,4,5,6,7,8} and B={1,3,4,6,7,8,9} then

If A=[(-3,1,6),(2,-5,0),(1,-3,4)],B=[(4,7),(-4,2),(-1,-5)] and AX=B, then the size of X is
