Translate the following inference to logic notation: For all x, x_3 will drive a car if and only if x_3 will play a game. For all x, if x_3 plays a game, then x_3 is reading a book. Therefore for all x, if x_3 drives a car, then x_3 is reading a book.
forall x: P(x) <-> Q(x). forall x: Q(x) -> R(x). Therefore forall x: P(x) -> R(x).
