Two pages that face each other in a book have 421 as the sum of their page numbers. What is the number of the page that comes first?

Respuesta :

Answer:the pages will come on the first is  210

Explanation:

Since we have given that two pages that face each other in a book

i.e. they must be consecutive to each other

so, let the first page number be x

and the second page number be x+1

According to question,

[tex]x+x+1=421\\2x+1=421[/tex]

2x=421 -1

2x=420

[tex]x=\frac{420}{2}\\=210[/tex]

So, the pages will come on the first is  210
