Given X cupY={1,2,3,4} , X cup Z={2,3,4,5}, X capY={2,3} and X cap Z ={2,4} , find X,Y and Z.

If X={1,2,3,4,5},Y={1,3,5,7,9} then find the value of X nn Y and (X-Y)uu(Y-X)

If 2x = 3y = 4z, find x:y: z.

[[2,5],[3,4]][[3,1],[-2,3]]=[[x,y],[1,z]] find x,y and z.

If x = 1, y = 2, z = 5 , then find the value of 3x – 2y + 4z.

If x = 2, y = 3 and z = -1, find the values of : (2x-3y+4z)/(3x-z)

If (x + y)/2 = (y+z)/3 = (z + x)/4 , then find x : y: z .

Let X={1,2,3,4,5). The number of different ordered pairs (Y,Z) that can formed such that Y sube X,Z sube X and Y nn Z is empty is

2x + 3y-5z = 7, x + y + z = 6,3x-4y + 2z = 1, then x =
