3 (x - y)
If x+y = 3 and y times x = 2 then y = 1.
Then y = 3x.
If y varies directly as x and y is 36 when x is 9, then y is always four times the value of x. So if y is 12, then x is 3.
Let one of the numbers be x and other be y.Sum is 33: x + y = 33 ...(1)Difference is 3: x - y = 3 ...(2)Let's add these equations:(x + y) + (x - y) = 33 + 32x = 36x = 18Putting the value of x in equation 1, we get18 + y = 33y = 33 - 18 = 15The two numbers are 18 and 15.15 and 18
