20 and 37 Or , algebraically speaking : x + y = 57 x - y = 17 Adding the two equations together then 2x = 74 and so x = 37 y = 57 - x and so y = 20
Or, not algebraically speaking: take the difference from the total and divide the result by two. This gives you the lowest number. Then add the difference to the lowest number and this will give you the higher number.
67 and 99
Subtract the difference and half your answer, giving 9 which is the smaller number, add the difference to this and you get 38 which is the larger number.
