Answer :
Final answer:
To find the left and right page numbers of an open book, solve the equation 2x + 1 = 221. The left page number is 110, and the right page number is 111.
Explanation:
To find the left and right page numbers of an open book, we need to solve the equation where the sum of the two consecutive integers is 221.
Let's assume that the left page number is x, so the right page number is x+1.
Therefore, our equation becomes x + (x+1) = 221.
By simplifying the equation, we get 2x + 1 = 221. Subtracting 1 from both sides, we have 2x = 220. Dividing both sides by 2, we find x = 110.
So, the left page number is 110, and the right page number is 111.
