Theorem bj-vtoclg1fv 37498
Description: Version of bj-vtoclg1f 37497 with a disjoint variable condition on 𝑥, 𝑉. This removes dependency on df-sb 2095 and df-clab 2740. Prefer its use over bj-vtoclg1f 37497 when sufficient (in particular when 𝑉 is substituted for V). (Contributed by BJ, 14-Sep-2019.) (Proof modification is discouraged.)
