Theorem simplbi2VD 39081

Description: Virtual deduction proof of simplbi2 655. The following user's proof is completed by invoking mmj2's unify command and using mmj2's StepSelector to pick all remaining steps of the Metamath proof.

h1::	|- ( ph <-> ( ps /\ ch ) )
3:1,?: e0a 38999	|- ( ( ps /\ ch ) -> ph )
qed:3,?: e0a 38999	|- ( ps -> ( ch -> ph ) )

The proof of simplbi2 655 was automatically derived from it. (Contributed by Alan Sare, 31-Dec-2011.) (Proof modification is discouraged.) (New usage is discouraged.)
