If `A=[[x,2,3],[-1,5,3]]` ,`B=[[1,-2,y],[1,z,-2]]` and `C=[[3,0,1],[0,2,1]]`, also `A+B-C=O` then find `x,y,z`

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

If A=[[1,2,-3],[5,0,2],[1,-1,1]],B=[[3,-1,2],[4,2,5],[2,0,3]] and C=[[4,1,2],[0,3,2],[0,-2,3]] verify that A(B+C)=AB+AC

If A=[[1,0,1],[3,1,2]],B=[[2,1,-4],[3,5,-2]], and C=[[0,2,3],[-1,-1,0]], verify that [A+2B+3C]^T=A^T+2B^T+3C^T

If X+Y=[[2,-1],[1,3],[-3,2]] and X-2Y=[[-2,-1],[-3,-1],[4,-2]] find X and Y.

Find x,y if [2,0,3]{3[[6,3],[-1,2],[5,4]]+2[[-4,-1],[1,0],[-3,-4]]}=[x,y]

Find x,y,z given that [[x],[y],[z]]=[[3,1,3],[2,0,2],[-5,1,-1]][[2],[4],[3]]

Let X=[{:(x_(1)),(x_(2)),(x_(3)):}],A=[{:(1,-1,2),(2,0,1),(3,2,1):}] and B=[{:(3),(1),(4):}] .If AX=B, then X is equal to: a) [(1),(2),(3)] b) [(-1),(2),(3)] c) [(-1),(-2),(3)] d) [(-1),(-2),(-3)]
