Consider the following premises. forall x_17: P_17(x_17) or Q_2(x_17). exists x_17: ~Q_17(x_17). forall x_17: P_17(x_17) <-> Q_17(x_17). forall x_17: W(x_17) -> ~Q_2(x_17). Can we infer forall x_17: W(x_17) -> ~Q_2(x_17) from them? If possible, name the inference rules being used at each step.
That is one of the premises. Therefore, the answer is yes.
