Theorem rspcedvdw 3583
Description: Version of rspcedvd 3582 where the implicit substitution hypothesis does not have an antecedent, which also avoids a disjoint variable condition on 𝜑, 𝑥. (Contributed by SN, 20-Aug-2024.)
Hypotheses
Ref Expression
rspcedvdw.s (𝑥 = 𝐴 → (𝜓 ↔ 𝜒))
rspcedvdw.1 (𝜑 → 𝐴 ∈ 𝐵)
rspcedvdw.2 (𝜑 → 𝜒)
Assertion
Ref Expression
rspcedvdw (𝜑 → ∃𝑥 ∈ 𝐵 𝜓)
Distinct variable groups:   𝑥,𝐴   𝑥,𝐵   𝜒,𝑥
Allowed substitution hints:   𝜑(𝑥)   𝜓(𝑥)
