Find x :

`[ x - 1 ] [ [ 1 , 0 ] , [ -2 , 0 ] ] = 0`

If [ [ 1 , 3 ] , [ 0 , 0] ] [ [ 2 ] , [ -1 ] ] = [ [ x ] , [ 0 ] ] , find the value of x

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

Find x, if [x-5-1][[1,0,20,2,12,0,3]]][[x41]]=O

If [[x, 4, 1]] [[2,-1,2] , [1,0,2] , [0,2,-4]] [[x], [4], [1]]=0 then find x

If [x1][[1,0-2,0]]=O, find x

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

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

find x, if [x" "-5" "-1][{:(1,0,2),(0,2,1),(2,0,3):}][{:(x),(4),(1):}]=0

If |[1,x,x^2] , [x,x^2,1] , [x^2,1,x]|=3 then find the value of |[x^3-1, 0, x-x^4] , [0,x-x^4, x^3-1] , [x-x^4, x^3-1, 0]|

If f(x)={:{(1-x", for " 0 lt x le 1), ( 1/2 ", for " x=0):} , then in [0, 1]
