Bridget�s classroom started out with a collection of only 6 books, but she plans to purchase an additional 3 books per week
n1= number of books

n1=6+3x

Cole�s library started out with 38 books, and he will purchase another 1 book per week

n2= 38+1x


When will n1 be equal to n2

6+3x = 38+x

3x-x = 38-6

2x = 32

x = 16

 amount of books in the two libraries will  be sam be the same at 16 weeks
