Theorem oveqrspc2v 7282

Description: Restricted specialization of operands, using implicit substitution. (Contributed by Mario Carneiro, 6-Dec-2014.)

**Hypothesis**
Ref	Expression
oveqrspc2v.1	⊢ ((𝜑 ∧ (𝑥 ∈ 𝐴 ∧ 𝑦 ∈ 𝐵)) → (𝑥𝐹𝑦) = (𝑥𝐺𝑦))

**Assertion**
Ref	Expression
oveqrspc2v	⊢ ((𝜑 ∧ (𝑋 ∈ 𝐴 ∧ 𝑌 ∈ 𝐵)) → (𝑋𝐹𝑌) = (𝑋𝐺𝑌))

Distinct variable groups: 𝑥,𝑦,𝐴 𝑥,𝐵,𝑦 𝑥,𝐹,𝑦 𝜑,𝑥,𝑦 𝑦,𝑌 𝑥,𝐺,𝑦 𝑥,𝑋,𝑦 Allowed substitution hint: 𝑌(𝑥)
