You have an amount of coins in your left pocket and an amount of coins in your right pocket. If you took one out of your right pocket and put it into your left pocket the amount in the right would be half of the left. If however you took one from the left pocket and put it in the right pocket both pockets would have equal amounts of coins. How many is in each pocket?

Just note that the coins aren't actually moved, its just what the totals would be if they were moved. Second is its the amount of coins, not the value.
