Theorem ovmpordx 49255

Description: Value of an operation given by a maps-to rule, deduction form, with substitution of second argument, analogous to ovmpodxf 7566. (Contributed by AV, 30-Mar-2019.)

Hypotheses

Ref	Expression
ovmpordx.1	⊢ (𝜑 → 𝐹 = (𝑥 ∈ 𝐶, 𝑦 ∈ 𝐷 ↦ 𝑅))
ovmpordx.2	⊢ ((𝜑 ∧ (𝑥 = 𝐴 ∧ 𝑦 = 𝐵)) → 𝑅 = 𝑆)
ovmpordx.3	⊢ ((𝜑 ∧ 𝑦 = 𝐵) → 𝐶 = 𝐿)
ovmpordx.4	⊢ (𝜑 → 𝐴 ∈ 𝐿)
ovmpordx.5	⊢ (𝜑 → 𝐵 ∈ 𝐷)
ovmpordx.6	⊢ (𝜑 → 𝑆 ∈ 𝑋)

Assertion

Ref	Expression
ovmpordx	⊢ (𝜑 → (𝐴𝐹𝐵) = 𝑆)

Distinct variable groups:   𝑥,𝑦,𝐴   𝑦,𝐵   𝑦,𝐴   𝑥,𝐵   𝑥,𝑆,𝑦   𝜑,𝑥,𝑦

Allowed substitution hints:   𝐶(𝑥, 𝑦)   𝐷(𝑥, 𝑦)   𝑅(𝑥, 𝑦)   𝐹(𝑥, 𝑦)   𝐿(𝑥, 𝑦)   𝑋(𝑥, 𝑦)
