**Reiny**, Sunday, May 12, 2013 at 10:56pmAdam --- 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.
