Bryan took a look at his books as well. He has 7 bookshelves with each having the same number of books. If he has a total of 28 books how many books are there in each bookshelf?
: 

Bryan has 7 bookshelves. 
Each bookshelf has the same number of books. 
Bryan has a total of 28 books. 

We can set this up as an equation: 

7x = 28 

We can solve for x by dividing both sides by 7: 

x = 4 

This means that each bookshelf has 4 books.
