If `|[x,4x,2],[1,7,3],[0,1,0]|=4`, then `x=?`.

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 [1, x, 2][[2,3,1],[0,4,2],[0,3,2]][[x],[1],[-1]]=0, then the value of x is

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

Solve for x: |[x^2+1,0,3x+2],[x,2,1],[4x,-1,0]|=0

If x+y=[[1,4,3] , [-2,5,6] , [7,0,2]] and x-y=[[3,2,5] , [4,1,2] , [1,0,4]] then find x and y

If 2[[3,4],[5,x]]+[[1,y],[0,1]]=[[7,0],[10,6]] then find (x-y)

If |[(x+3y),y],[7-x,4]|=[(4,-1),(0,1)], find the values of x and y.
