Every day 7 pages

Adelka reads the book every day 7 pages. When she reads one more page a day she will read it three days earlier. How long will Adelka read a book? How much does a book of pages have?

Result

d =  24 d
s=##:  168

Solution:

7d = s
(7+1)*(d-3) = s

7d-s = 0
8d-s = 24

d = 24
s = 168
