Marge has 4 more than 2 times as many books as Susan. If Marge has 22 books and x is the number of books that Susan has, the relationship can be written as 4 + 2x = 22. How many books does Susan have?
Susan has 9 books. If the equation is 4+2x=22 Then you would first subtract 4 from 22 and get 18. Then you divide 2 from 18 and get 9, your answer. If you need me to explain it more, just ask!
