Consider the following premises. forall x_15: Q_15(x_15) -> P_15(x_15). Q_15(e) -> p. p -> t. forall x_15: P_15(x_15) -> Q_15(x_15). Can we infer forall x_15: Q_15(x_15) -> P_15(x_15) from them? If possible, name the inference rules being used at each step.
That is one of the premises. Therefore, the answer is yes.
