Consider the following premises. forall x_17: T_2(x_17) -> P_3(x_17). forall x_17: P_12(x_17) -> ~Q_12(x_17). exists x_17: Q_12(x_17). forall x_17: P_3(x_17) -> T_2(x_17). forall x_17: P_12(x_17) <-> T_2(x_17). Can we infer forall x_17: P_3(x_17) -> T_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.
