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

Solve: 2X+Y+[[-2,1,3],[5,-7,3],[4,5,4]]=0,X-Y=[[4,7,0],[-1,2,-6],[-2,8,-5]] .

If [[ 2 x , 5],[ 8 , x ]] = [[6 , -2 ],[7 , 3 ]], then, x=

Solve for x : |(x-2,2,5),(x-7,3,6),(2x-6,4,7)|=0

solve : |{:(x-2,2,5),(x-7,3,6),(2x-6,4,7):}|=0

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

the [[x-2,2,5x-7,3,62x-6,4,7]] = 0
