Translate the following inference to logic notation: For all x, if x_5 plays tennis, then x_5 is working. For all x, x_5 will play tennis. For all x, x_5 is a scientist and x_5 is a musician. Therefore for all x, x_5 will work and x_5 is a scientist.
forall x: P(x) -> Q(x). forall x: P(x). forall x: R(x) and S(x). Therefore forall x: Q(x) and R(x).
