Question 1105656: "sum of two numbers is 120 The difference between them is 12
Answer by Theo(13342) (Show Source): You can put this solution on YOUR website!
x + y = 120
x - y = 12
add the 2 equations together to get 2x = 132
divide both sides of this equation by 2 to get x = 66.
since x - y = 12, then y = x - 12 = 66 - 12 = 54.
you have x = 66 and y = 54.
x + y = 66 + 54 = 120
x - y = 66 - 54 = 12
solution looks good.
solution is x = 66 and y = 54.
