Evaluate : `[[1,3,5]][[1,0,3],[2,0,1],[0,1,2]][[1],[4],[6]]`

" Evaluate the following: "[[1,2,3]][[1,0,2],[2,0,1],[0,1,2]][[2],[4],[6]]

Find x and y , if 2[[1,3],[0,x]]+[[y,0],[1,2]]=[[5,6],[1,8]]

Evaluate the following : [[1,-1],[0,2],[2,3]]([[1,0,2],[2,0,1]]-[[0,1,3],[1,0,2]])

Find x and y if 2[[2,3],[0,x]]+[[y,0],[1,3]]=[[5,6],[1,8]]

Compute the following: [[2,3,1],[5,-1,2],[0,3,5]]+[[1,-2,3],[-3,1,5],[6,2,0]]

Find x and y, if 2[[1, 3],[ 0,x]]+[[y,0], [1, 2]]=[[5, 6],[ 1, 8]]

If A=[[1,2,3],[-1,0,2],[1,-3,1]], B=[[4,5,6],[-1,0,1],[2,1,2]], C=[[-1,-2,1],[-1,2,3],[-1,-2,2]] find A-2B+3C. Also verify that (A+B)+C=A+(B+C).

8.Find the rank of the matrix [[0,1,-3,-1],[1,0,1,1],[3,1,0,2],[1,1,-2,0]]

Find the Rank of the matrix [[1,2,-1,0],[-1,3,0,-4],[2,1,3,-2],[1,1,1,1]]

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