Adam --- x apples Bob ---- y apples x+39 = 2y or x - 2y = -39 2x = y + 39 or 2x - y = 39 the first equation: x - 2y = -39 double the 2nd : 4x - 2y = 78 subtract them: 3x = 117 x = 39 into the 2nd: 78 - y = 39 -y = -39 y = 39 They each picked 39 apples.

The rule is to choose a near number that is easier to add. Rounding to nearest 5 will work. For instance, add 3+17+21+12 using compatible numbers 5+15+20+10=50 The use of compatable numbers is an aid to doing arithmetic. It works not as good on multiplying and dividing, but it...
