Theorem simplbi2VD 42466

Description: Virtual deduction proof of simplbi2 501. 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::	⊢ (𝜑 ↔ (𝜓 ∧ 𝜒))
3:1,?: e0a 42392	⊢ ((𝜓 ∧ 𝜒) → 𝜑)
qed:3,?: e0a 42392	⊢ (𝜓 → (𝜒 → 𝜑))

The proof of simplbi2 501 was automatically derived from it. (Contributed by Alan Sare, 31-Dec-2011.) (Proof modification is discouraged.) (New usage is discouraged.)
