A student opens a math book to two facing pages.The product of the page numbers is 210.Find the page numbers.
The first page is _________
The second page is________

You could appoach this one of two ways. First, it could be a two equation solution. You know that the product of the two numbers is 210 so your first equation would be x * y = 210 You also know that X and Y will only be one number apart, so your second equation could be y = x + 1 The you can subsitute what y equals into the first equation so x * (x+1) = 210 and proceed to solve this equation for X.
The second approach is just trial and error. 
the answer is page 14 and 15. If you times them together you get 210. Hop this helps
