PROBLEM #1: Farmer Ben has only ducks and cows. He can't remember how many of each he has. Well, he doesn't need to remember because he knows he has 22 animals and that 22 is also his age. He also knows that the animals have total of 56 legs, because 56 is also his father's age. Assuming that each animal has all legs intact and no more, how many of each animal does Farmer Ben have?
