The sum of the page numbers on facing pages of a book is $373$$. What are the page numbers.
Given: The sum of the page numbers on facing pages of a book is $373$.
To do: To find the page numbers.
Solution:
Let the first page be "$x$" and the second page be "$x+1$"
Sum of page numbers$=373$.
$\Rightarrow x + x+1=373$
$\Rightarrow 2x+1=373$
$\Rightarrow 2x=373 - 1$
$\Rightarrow 2x=372$
$\Rightarrow x=\frac{372}{2}$
$\Rightarrow x=186$
Thus, the pages are $x=186$ and $x+1=186+1=187$.
