Example: Wu Jing was a mathematician in my country's Ming Dynasty and the author of "Nine Chapters on Algorithms and Analogies". One of his poems is still circulating today.

The towering pagoda is seven stories high.

Dots of red lights multiply.

There are three hundred and eighty-one lanterns in total,

How many lights are there on the top floor?

The meaning of this poem is: a majestic seven-story pagoda, with red lights flashing on the eaves. The number of red lights on the lower floor is twice that of the adjacent upper floor. If there are 381 lights in total, how many lights are on the top floor?

The general process of using equations to solve practical problems is:

1. Review the question: Analyze the meaning of the question and find out the known quantities, unknown quantities in the question and the equivalent relationship between each quantity;

2. Assume the element: Assume the unknown number and use it to represent other unknown quantities;

3. List equations: List equations based on equality relationships;

4. Solve the equation and check whether the solution of the equation is correct and consistent with the meaning of the question;

5. Answer: Write the answer.

Consolidation exercises

A total of 128 tickets were sold at the water park on a certain day, with a revenue of 912 yuan. The ticket price is 10 yuan per adult, and students can enjoy a 40% discount. How many adult and student tickets are sold on this day?

6 people sit in a circle, each person thinks of a number in his mind, and tells the number to the people adjacent to the left and right. Then each person shows the average of the numbers told to him by the two adjacent people on the left and right (as shown in the picture). Ask the person who showed 11 what number they originally had in mind.
