If `X + [ [ 2 , 1 ] , [ 6 , 1 ] ] = [ [ 1 , 1 ] , [ 0 , 1 ] ] ` , then find X is equal to

If X + [ [ 2 , 1 ] , [ 6 , 1 ] ] = [ [ 1 , 1 ] , [ 0 , 1 ] ] , then X is equal to ( 1 ) [ [ 0 , 1 ] , [ 0 , 6 ] ] ( 2 ) [ [ 0 , -1 ] , [ 0 , - 6 ] ] ( 3 ) [ [ -1 , 0 ] , [ - 6 , 0 ] ] ( 4 ) [ [ 1 , 0 ] , [ 6 , 0 ] ]

If [ [ 1 , -2 ], [ 8 , x ] ] = [ [ 1 , -2 ] , [ 8 , 6 ] ] , then x is equal to :

If A=[[x,1]][[1,0],[-2,0]] =0 , then x is equals to

If |[1,2,x],[1,1,1],[2,1,-1]|=0" then find x

If A=[(2,1),(0,x)] and A^(-1)=[(1/2,1/6),(0,1/x)] , then the value of x is equal to

If X+{:[(2,1),(6,1)]:}={:[(1,1),(0,1)]:} then 'X' is equal to

If [(x,1)][(1,0),(-2,0)] = 0, then x equals

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

" If the trace of the matrix: "A=[[-1,0,2,5],[3,x^(2)-2,4,1],[-1,-2,x-3,1],[2,0,4,x^(2)-6]]" is "0" then "x" is equal to "
