DAY 39
If I give you $1, we'll each have the same amount of money. If you give me $1, I'll have twice as much as you. How much does each one of us have?

Answer:

I have $7 and you have $5.......If giving you $1 will make us even, I must have two dollars more than you. Let X = lesser amount and X + 2 = greater amount.
(X + 2) + 1 =2 (X - 1)
