Theorem ovmpordx 48184

Description: Value of an operation given by a maps-to rule, deduction form, with substitution of second argument, analogous to ovmpodxf 7582. (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
