Answer:
The number of pages in the U.S. Tax Code is 20,000.
Step-by-step explanation:
Designate T as the number of pages in the U.S. tax code.
Let B represent the number of pages in the King James Bible.
The U.S. tax code's pages exceed the Bible's by 18,528.
This can be translated to mean that the U.S. tax code has 18,528 pages more than the Bible.
This is expressed mathematically as:
..........(1)
The total number of pages between the tax code and the Bible is 21,472.
......... (2)
Next, replace T in equation (1) into equation (2)

=> 
=> 
Giving us B=1,472 (Bible pages)
And T =
= 20,000
Conclusively, the U.S. tax code contains 20,000 pages.
