The sum of the page numbers on the facing pages of a book is 73. What are the page​ numbers?

Question

how do you solve this?(with step by step answers)

Answer 1

They are consecutive pages.  If the first page number is n, the next page number is n + 1.

 

n + (n + 1) = 73

 

Solve for n.

 

2n + 1 = 73

 

n = (73 - 1)/2 = 72/2 = 36

 

The page numbers are 36 and 37.
