Write a "solution" in the application problem as a whole, and the formulas listed by yourself should generally be written as "solution, gain". Let me take an application problem as an example to talk about the standard problem-solving format.

The first step is to analyze the overall idea after reading the topic, and then write a "solution" as a whole. As shown in the figure below:

Step 2: After analyzing the topic, set an unknown number and make an equation according to the set unknown number, as shown below:

The third step is to write a "solution" after listing the equations. The calculation process of the formula is completed on draft paper, and finally only a result is written. As shown in the figure below:
