Question

The sum of the page numbers on the facing pages of a book is 373 what are the page numbers hint that the page numbers of open pages are X and X + 1

Answer 1

$x + (x + 1) = 373 \\ x + x + 1 = 373 \\ 2x = 373 - 1 \\ x = \frac{372}{2} \\ x = 186 \\ \\ two \: numbers \: are \: 186 \: and 187$

Answer 2

X+X+1=373

2x+1=373

2x=372(or)X=372/2

X=186

X+1=186+1=187
