1、2x + 5 = 10

2、7x - 3x = 24

3、 12 - 5y = 7

4、x + 4/5 = 9/ 10

5、3(x + 2) = 5(x + 1)

Solution:

1, read the topic carefully: First, read the topic carefully to understand the conditions given by the topic and the problems to be solved.

2. Organize the equation: organize the equation into a standard form, that is, move all terms to one side of the equation and set the other side of the equation to 0.

3. Solving the unknown: according to the characteristics of the equation, choose the appropriate solution to solve. Some equations may need to be simplified or deformed, while others can be solved directly.

4. Integrate the answer: substitute the obtained unknown value into the original equation for testing to ensure the correct solution. Finally, integrate the answers and write out the problem-solving process and answers.

It should be noted that when solving the equation, we should pay attention to the operation order and symbols to avoid mistakes. At the same time, we should be good at summing up laws and methods to improve the efficiency of solving problems.

How to study mathematics

1. Establish a mathematical foundation: the knowledge of mathematics is gradually established. For beginners, it is suggested to learn basic mathematical knowledge such as algebra, geometry and trigonometric functions first.

2. Understanding concepts: Learning mathematics requires understanding concepts, not memorizing them. The concept of mathematics is often abstract and needs to be understood through concrete examples.

3. Practical skills: Learning mathematics requires practical skills, such as problem-solving skills and calculation skills. It is suggested to practice your skills by doing exercises.

4. Learning strategy: When learning mathematics, you need to learn how to apply what you have learned to practical problems and how to solve them.

5. Find good learning resources: When learning mathematics, you can make use of some good learning resources, such as textbooks, online courses and math games.

6. Communicate with people: When studying mathematics, you can communicate with people. Communicating with others can help us understand the problem and solve it with the help of others' experience.

7. Establish good study habits: Learning mathematics requires establishing good study habits, such as reviewing regularly, taking notes and doing problems. Good study habits can help you master knowledge and skills better.

8. Pay attention to your own mistakes: When learning mathematics, you should pay attention to your own mistakes and analyze the reasons for them so as to correct them better.

9. Keep a positive attitude: You need to keep a positive attitude when learning mathematics, and don't give up easily. I believe that I can overcome difficulties and achieve good results.

In a word, learning mathematics requires a lot of hard work and practice. I hope the above suggestions can help you learn math better.
