1, read the meaning of the question and simplify the irrelevant language. The current application problem is not mathematics, but the reading ability of Chinese, and it also needs the ability to transform the problem.

2, cleverly set the unknown. Several quantities can be set as unknowns in an application problem, but which one is more convenient should be carefully considered. For example, the speed ratio between Party A and Party B is 3: 2. When calculating the speed of Party A and Party B, we can set the speed of Party A as km/h and the speed of Party B as km/h, which is a binary linear equation set. Or let the speed of A be 1 km/h and B be 2/3 km/h, which is a linear equation, but it has a fraction; Or let the speed of A be 3 km/h and the speed of B be 2 km/h..

So the last way is the best. Set unknowns according to different topics.

3. List the equations according to the equivalence relation.

4. Solve the equation. At this time, we may encounter two unknowns and only list one equation. We need to see if there are any implicit conditions, such as the number of people and the number of objects, which are all positive integers. This is an implicit condition, especially used in inequality equations. There is also the need to test the roots of fractional equations.

5. Write clearly the unit and the answer. This step is often overlooked. In fact, this step only reflects whether you have read the topic, whether you know the requirements of the topic, and whether you want to score in the exam.

6. Practice makes perfect. Draw inferences, draw inferences.

This is my personal experience in docking application problems, and I hope it will help you. A little experience
