Translate the following inference to logic notation: For all x, if x_7 works, then x_7 is a musician. For all x, if x_7 works, then x_7 is playing a game. For all x, if x_7 were a musician, then x_7 is working. For all x, x_7 will not work. For all x, if x_7 plays a game, then x_7 is a musician. Therefore for all x, x_7 is not a musician.
forall x: P(x) -> Q(x). forall x: P(x) -> R(x). forall x: Q(x) -> P(x). forall x: ~P(x). forall x: R(x) -> Q(x). Therefore forall x: ~Q(x).
