We can certainly simplify that term. 6x - 3x = 3x. And -4y + y = -3y. So the simplified expression is 3x-3y. You could also call this 3(x-y). That's as far as we can go, since we have no way to evaluate x or y without further information.

The sum of two numbers is 84 One number is three times the other What are the numbers?
lets call the one number X and the other Y so y equals 3X so 3X plus X equals 84 so 4X equals 84 we divide by 4 so x equals 21 so y equals 21 times 3 equals 63 so the two numbers are 63 and 21
