Translate the following inference to logic notation: For all x, if x were an artist, then x is fast. For all x, x will sleep. For all x, if x plays squash, then x is fast. For all x, x is an artist or x will play squash. Therefore for all x, x is fast.
forall x: P(x) -> Q(x). forall x: R(x). forall x: S(x) -> Q(x). forall x: P(x) or S(x). Therefore forall x: Q(x).
