A book has 24 chapters. The second chapter is 12 pages long. If there are a total of 44 pages in the book How many pages are in the first chapter?
There are 24 chapters in the book. 
The second chapter is 12 pages long. 
That means that there are a total of 44 pages in the book. 

Now we just have to solve for the number of pages in the first chapter. We can do this by setting up an equation: 

x + 12 = 44

x = 32

So, the first chapter is 32 pages long.
