There are 30 books in a bookcase. The books in the bookcase are all poetry, history, and art books. Ten of the books are art books. There are 6 fewer poetry books than history books. How many poetry books are in the bookcase?

30 - 10 art books = 20

20 - 6 = 14

14/2 = 7 poetry books

7 + 6 = 13 history books
