The Sumner family has 5 children. Patty is 7 years younger than her older brother, Adam. Tracy and Adam are twins. Janelle is half as old as Patty. Brian, who is 13, is 6 years older than Janelle. How old is Adam?

OpenStudy (anonymous):

If Brian is 6 years older than Janelle, that means Janelle is 6 years younger. So to find Janelle's age, just subtract 6 from Brian's age, which is 13.

Right. And if Patty is 7 years younger than Adam, Adam is 7 years older. So can you figure out Adam's age then?
