列方程解应用题是初中代数的一个重点，也是一个难点．难关主要有两个：一个是将普通语言翻译为数学语言，这对初一学生来说是一个难关，另一个是将实际问题转化为数学问题──方程问题，即能正确地找出应用题中的相等关系，并据此列出方程，这是问题的关键所在．只要突破这一 The application of the solution of column equations is a key point of junior high school algebra, and it is also a difficult point. There are two major difficulties: one is the translation of common language into a mathematical language, which is a difficult one for junior students, and the other is to convert practical problems into mathematical problems-equation problems, that is, to correctly find out the problems The equipotential relationship in the equation is listed accordingly, which is the key to the problem.
