列方程解应用题是以常见的数量关系为主导、为基础,以其数量之间的相等关系为前提,以设项为辅助,让未知数x与已知数处于同等的地位和关系参加列式,列方程时,找出题中隐含的等量是列方程解应用题的关键。如何“捕捉”题目中的等量关系呢?现从以下几方面进行研讨。一、用常见的数 Column equation solution to the problem is dominated by the number of relations as the basis, based on the equal relationship between the number of premise, with the project as an aid to the unknown number x and known number in the same position and the relationship to participate in the formula , Column equations, finding the implied equivalent of the problem is the key to solving the column equation solution. How to “capture” the subject of the same amount of relations? Now from the following aspects of research. First, with the common number
