the comic has n books.

 

like melody said:

 

(n:2) + 10 = 24

 

24 - 10 = 14

 

solve 14 * 2

 

this should be easy for you.

 

thanks.

Okay, first we need to look at the question. If William NOW has 24 comic books, including the recently bought books and the previosly sold books. Our equation could look like this:

24 = (C / 2)+ 10

With the variable C being the amount of comic books William had before. We can solve this by subtracting 10 from 24 (24 - 10), to get 14 and multiply that by 2 to get 28 comic books. So, in summary, William would had have 28 comic books to begin with.
