Answer to Question #130787 in Algebra for Bri

Question

The left and right page numbers of an open book are two consecutive integers whose sum is 541.Find these page numbers.

Answer 1

Let $x$ be the left page number, then $x+1$ is the right page number.

We have $x+(x+1)=541$, that is $2x+1=541$. So $x=\frac{541-1}{2}=270$ and $x+1=271$

Answer: $270, 271$
