`[[x+1,2,3],[1,x+1,3],[3,-6,x+1]] = 0`

If |[ x+1 ,2 ,3],[1 , x+2,3],[1, 2, x+3]|=0 , then x=0 and

Solve for x: /_\=|[2x,3,1],[4,6,x],[3x,1,1]| = 0

|[x,-6,-1],[2,-3x,x-3],[-3,2x,x+2]| =0

If A = [[x,1,-x],[0,1,-1],[x,0,7]] and det (A) = |(3,0,1),(2,-1,0),(0,6,7)| , then the value of x is a)-3 b)3 c)2 d)-8

If A=[[1/3,2],[0,2x-3]] , B=[[3,6],[0,-1]] and AB=I ,then x=

Solve for x , |[x,-6,-1], [ 2,-3x,x-3], [-3, 2x, x+2]| =0.

Solve for x , |[x,-6,-1], [ 2,-3x,x-3], [-3, 2x, x+2]| =0.

If |[x,-6,1],[2x,-3,3],[0,1,2]| =0 find the value of x

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

If the trace of the matrix A= [{:( x-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
