Theorem eloprabga 5578

Description: The law of concretion for operation class abstraction. Compare elopab 4696. (Contributed by NM, 14-Sep-1999.) (Revised by David Abernethy, 18-Jun-2012.) Removed unnecessary distinct variable requirements. (Revised by Mario Carneiro, 19-Dec-2013.)

Hypothesis

Ref	Expression
eloprabga.1	⊢ ((x = A ∧ y = B ∧ z = C) → (φ ↔ ψ))

Assertion

Ref	Expression
eloprabga	⊢ ((A ∈ V ∧ B ∈ W ∧ C ∈ X) → (⟨⟨A, B⟩, C⟩ ∈ {⟨⟨x, y⟩, z⟩ ∣ φ} ↔ ψ))

Distinct variable groups:   x,y,z,A   x,B,y,z   x,C,y,z   ψ,x,y,z

Allowed substitution hints:   φ(x,y,z)   V(x,y,z)   W(x,y,z)   X(x,y,z)

Proof of Theorem eloprabga

Dummy variable w is distinct from all other variables.
