Theorem bdceqir 17075

Description: A class equal to a bounded one is bounded. Stated with a commuted (compared with bdceqi 17074) equality in the hypothesis, to work better with definitions ( B is the definiendum that one wants to prove bounded; see comment of bd0r 17056). (Contributed by BJ, 3-Oct-2019.)

Hypotheses
