Theorem ovidig 7531

Description: The value of an operation class abstraction. Compare ovidi 7532. The condition (𝑥 ∈ 𝑅 ∧ 𝑦 ∈ 𝑆) is been removed. (Contributed by Mario Carneiro, 29-Dec-2014.)

Hypotheses

Ref	Expression
ovidig.1	⊢ ∃*𝑧𝜑
ovidig.2	⊢ 𝐹 = {⟨⟨𝑥, 𝑦⟩, 𝑧⟩ ∣ 𝜑}

Assertion

Ref	Expression
ovidig	⊢ (𝜑 → (𝑥𝐹𝑦) = 𝑧)
