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

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

2x + 3y + 3z = 5, x-2y + z = -4,3x-y-2z = 3

If ( x - 1 )^3 + ( y - 2 )^3 + ( z - 3 )^3 = 3 ( x - 1 ) ( y - 2 ) ( z - 3 ) and x - 1 != y -2 != z-3 , then x + y + z is equal to : ( A ) 2 ( B ) -6 ( C ) 6 ( D ) 4

If x/((2x+y+z))=y/((x+2y+z))=z/((x+y+2z))=a , then find a if x+y+z!=0 . (a)1/3 (b) 1/4 (c) 1/2 (d) 1/8

If (x)/(2a-3b)=(y)/(3b-4c)=(z)/(4c-2a) , then find the value of x^(3)+y^(3)+z^(3) .

If x:y=2:3 and y:z=2:3, then x:z=2:3(b)3:4(c)5:7 (d) 4:9
