The problem of solving equations in grade six usually examines students' understanding and calculation ability of linear equations and quadratic equations. Common topics of error-prone equations are as follows:

1、2x + 7 = 17，3x - 8 = 16，5x - 20 = 3x + 10，2(x - 3) = 5x - 2，3(2x + 1) - 2(x - 3) = 18，x + 3/2 = 7/3，3(x - 4) = 2(x + 5) - x，3x+5 = 2x-65433

2 、( x+2)/(x+3)+(x-6)/(x-7)=(4x+8)/(x？ -9) Students may make some common mistakes in solving these equations, such as forgetting to shift terms, improper simplification of coefficients, and ignoring discriminant when solving quadratic equations with one variable. Students need to pay attention to these error-prone points and check them carefully when solving problems to ensure that they get the correct answers.

3. Find the coefficient of the unknown quantity: when solving the equation, first ask for the coefficient of the unknown quantity. If the unknown appears on one side of the equation, then the number in front of it is its coefficient. For example, in equation 2x+5 = 7, the coefficient of x is 2. Changing the coefficient of unknown quantity into 1: Changing the coefficient of unknown quantity into 1 can solve the equation more easily.

Precautions for Xiaoshengchu

1. Be mentally prepared: junior high school is a new stage. Students need to be prepared to accept new knowledge and new environment. Parents need to be psychologically prepared, and don't give their children too high expectations and pressure. Understand the policy: Students and parents need to understand the policies and processes of junior high school, especially for foreign students and students studying in different places, and need to know the relevant policies and requirements in advance.

2. Make plans: Students need to make their own study plans and goals, and parents need to help their children plan their future development direction according to their actual situation and hobbies. Adjusting learning methods: junior high school is a new stage. Students need to adjust their learning methods and pay attention to mastering basic knowledge and improving their application ability.

3. Actively participate in activities: junior high school is a transitional stage, and students need to actively participate in various activities, such as academic competitions, social practice, volunteer activities, etc. , improve their comprehensive quality and ability. Communication with teachers: Students need to keep good communication with teachers, keep abreast of their learning situation and problems, and actively seek help and guidance.
