Translate the following inference to logic notation: For all x, x_5 is a musician or x_5 will take a plane. For all x, if x_5 takes a plane, then x_5 is playing tennis. For all x, if x_5 were a musician, then x_5 is playing tennis. For all x, if x_5 plays tennis, then x_5 is taking a plane. Therefore for all x, x_5 will play tennis.
forall x: P(x) or Q(x). forall x: Q(x) -> R(x). forall x: P(x) -> R(x). forall x: R(x) -> Q(x). Therefore forall x: R(x).
