Translate the following inference to logic notation: For all x, x_8 is a janitor or x_8 will not play squash. For all x, if x_8 were an artist, then x_8 is not a janitor. For all x, x_8 will play squash. For all x, if x_8 were a mechanic, then x_8 is a janitor. Therefore for all x, x_8 is not an artist.
forall x: P(x) or ~Q(x). forall x: R(x) -> ~P(x). forall x: Q(x). forall x: S(x) -> P(x). Therefore forall x: ~R(x).
