Two consecutive page numbers in a book add up to 215. Find the page numbers

Question

word problem in mathematics 

Answer 1

Hello Kari,

So, let's assign x to the first page number and x + 1 to the very next page "consecutive page numbers in a book."

Now, you can form an equation. 

x + x + 1 = 215   "Two consecutive page numbers in a book add up to 215."

Now, solve your equation. 

2x + 1 = 215 

2x = 214  <---subtract 1 from both sides of your equation. 




x = 107  

x + 1 = 108 

Now, check our work. Does 107 added to 108 equal 215? 

107 + 108 = 215

215 = 215 

Yes, it checks.
