Pages of book

Lenka calculated that if every day to read 16 pages of the book, read a book a day earlier than had read only 14 pages a day. How many pages has this book?

Correct answer:

n =  112

Step-by-step explanation:


16(d-1) = n
14 d = n

16•(d-1) = n
14•d = n

16d-n = 16
14d-n = 0

d = 8
n = 112
