Exemple !

John has read 10 pages on the first day, on the second day he has read 5 pages with 2 pages more than half of the book. How many pages does the book have?

Solution. First we find out how many pages half of the book has

10 + 5 - 2 = 13

If we know that half of the book has 13 pages, the number of pages the book has in total is made up of the sum of the two half's.
