Question

he left and right page numbers of an open book are two consecutive integers whose sum is 407.  Find these page numbers.

Answer 1

The page numbers of book are 203 and 204.

Step-by-step explanation:

Let,

the two consecutive integers are;

x, x+1

Sum of integers = 407

$x+(x+1)=407\\x+x+1=407\\2x=407-1\\2x=406$

Dividing both sides by 2

$\frac{2x}{2}=\frac{406}{2}\\x=203$

Therefore,

the two integers are;

x = 203

x+1 = 203+1 = 204

The page numbers of book are 203 and 204.
