方程是初中数学的一个重要内容,利用方程的方法是解决函数、几何等有关问题的重要方法之一,而利用方程模型是解决实际问题的重要手段.它是中考的热点,也是历年中考每卷必考的重点内容.这部分知识内容涉及的考点主要有:一元一次方程、二元一次方程组、可化为一元一次方程的分式方程、一元二次方程的解法以及列方程(组)解决实际问题.一、中考内容要求1.能够根据具体问题中的数量关系,列出方程
Equation is an important part of junior high school mathematics, and the method of using equation is one of the most important ways to solve the problem of function and geometry.Using the equation model is an important way to solve practical problems.It is also a hot spot of senior high school entrance examination, The key content of the exam will be included in this part of the knowledge content of the test sites are: a linear equation, bivariate equations, can be transformed into a unitary equation fractional equation, a quadratic equation solution and column equation (group) solution Practical problems First, the exam content requirements 1. According to the specific relationship between the number of issues, list the equation
