If x, y, z are positive integers, such that xy + x + y = 215, yz + y + z = 161 and zx + z + x = 107, then (y – z)/(x – z) =

If x, y, z are three positive numbers such that (A - x): (A - y): (A - z) = 1: 7: 4 and 2A = x+y+z, then x:y:z= ?

If y/(x - z) = (y + x)/z = x/y then find x : y : z ?1 : 2 : 33 : 2 : 14 : 2 : 32 : 4 : 7

Divide. Enter your solution as a mixed number.6,132 ÷ 203 = (Enter all mixed numbers as x y/z.)
