Angus, Patrick, and Ollie went fishing for trout on Rainbow Lake. Angus caught 4 more fish than Patrick did, but Ollie caught 7 fewer fish than Angus. If Ollie caught 5 fish, how many fish did Patrick catch?

How many fish did Angus catch? ** If Ollie caught 7 less than Angus, then Angus caught 5+7=12 fish.
How many fish did Patrick catch? ** And since Angus caught four more than Patrick, then Patrick caught 12-4=<<12-4=8>>8 fish.
