Theorem rabbidv 2810
Description: Equivalent wff's yield equal restricted class abstractions (deduction form). (Contributed by NM, 10-Feb-1995.)
Hypothesis
Ref Expression
rabbidv.1  |-  ( ph  ->  ( ps  <->  ch )
)
Assertion
Ref Expression
rabbidv  |-  ( ph  ->  { x  e.  A  |  ps }  =  {
x  e.  A  |  ch } )
Distinct variable group:    ph, x
Allowed substitution hints:    ps( x)    ch( x)    A( x)
