The sum of the page numbers on the facing pages of a book is 285. Find the larger page number.

Let the larger page number be x

Then smaller page number will be x - 1 as both the pages are facing pages.

Given sum of pages is 285

Therefore equation x + x - 1 = 285

Now we will solve this equation

2x - 1 = ...
