The school awarded a batch of books to outstanding young pioneers, 6 books were short of 2 1 and 5 books were short of 3. Q: How many books are there? How many outstanding young pioneers are there?
We can do this problem in two ways: equation and formula.

Tip: To list equations, you must keep the total number of people or books unchanged before you can list equations.

Equation: Solution: Let * * have X outstanding young pioneers, then the equation can be listed as follows:

6x-2 1=5x-3。 Move the project to get:

x= 18。

Then, a * * * has a book: 18×5-3=87 (Ben).

A: A * * * has 87 books, which were written by 18 young pioneers.
