What would happen if two black holes that are equal in every way were right next to each other?

Outside the event horizon, the gravitational effects of a black hole are the same as those of a regular object of the same mass so if their event horizons don't overlap, they attract each other like any other two objects with mass. As for what happens when they are close enough to overlap....I'll let someone more knowledgeable answer that.
