How to write this python program, please write down the programming and ideas, thank you.

This is actually solving a linear equation.

Suppose you can drink x bottles of beer, x empty bottles can be exchanged for x/2 bottles of beer without paying, and x bottle caps can be exchanged for x/4 bottles of beer without paying.

So, the equation is:

(x-x/2-x/4)*2= 10

The specific code is as follows:

x=4

Although correct:

if (x-x/2-x/4)*2== 10:

Print (x)

break

x+=4

The following is a screenshot of the operation:
