Theorem sbsbc 3167
 Description: Show that df-sb 1660 and df-sbc 3164 are equivalent when the class term in df-sbc 3164 is a set variable. This theorem lets us reuse theorems based on df-sb 1660 for proofs involving df-sbc 3164. (Contributed by NM, 31-Dec-2016.) (Proof modification is discouraged.)
