Hi, I have no idea how to begin constructing this proof, and I would appreciate any help!

I need to prove the following, and to make matters worse, without soundness or completeness

⊢ (∀x.ϕ) →(∃x.ϕ)

I can use the following axioms/theorems http://img233.imageshack.us/img233/5...11115at824.png Thank you.

Please note that any sort of help to get me started on the proof would be very helpful.
