If the sum of two numbers is 6 and there difference is -2 what are the two numbers?
Let numbers be x and y. Then, x + y = 6 x - y = -2 add up both equations 2x + y - y = 6 + (-2) 2x = 4 divide by 2 to both sides x = 2 Since the sum of the numbers is 6 and one of the numbers is 2, then the other number is 4 (6 - 2). Check: 2 + 4 = 6 2 - 4 = -2
