Question

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?

Answer 1

Susan has 9 books

Explanation:

• Step 1: Given the relationship between the number of books that Susan and Marge has, find x.

4 + 2x = 22

2x = 18

x = 18/2 = 9

⇒ Number of books that Susan has is 9
