In a four-team basketball league, each team has played every other team 4 times. A team earned 3 points for a win, 1 point for a tie and no points for a loss. The total accumulated points were: Bulls 22, Lakers 19, Knicks 14 and Warriors 12. How many games ended in a win and how many games ended in a tie? (Hint: you might want to start by figuring out how many games total were played, how many points were available, and the combinations of how the teams received the points.)
