Theorem ov6g 6107

Description: The value of an operation class abstraction. Special case. (Contributed by NM, 13-Nov-2006.)

Hypotheses

Ref	Expression
ov6g.1	|- ( <. x , y >. = <. A , B >. -> R = S )
ov6g.2	|- F = { <. <. x , y >. , z >. | ( <. x , y >. e. C /\ z = R ) }

Assertion

Ref	Expression
ov6g	|- ( ( ( A e. G /\ B e. H /\ <. A , B >. e. C ) /\ S e. J ) -> ( A F B ) = S )

Distinct variable groups:   x, y, z, A   x, B, y, z   x, C, y, z   z, R   x, S, y, z

Allowed substitution hints:   R( x, y)   F( x, y, z)   G( x, y, z)   H( x, y, z)   J( x, y, z)

Proof of Theorem ov6g

Dummy variable w is distinct from all other variables.
