列一元一次方程解应用题是“一元一次方 程”这章的一个重点,也是一个难点．难就难在 怎样寻找一个能反映题目全部含义的相等关 系．因此,突破这一难点的关键是学会寻找相 等关系,那么怎样寻找相等关系呢?现结合实例 介绍三条途径,供同学们学习时参考． 途径之一:根据题中的关键语句来寻找相 等关系 列一元一次方程解应用题是“一元一次方 程”这章的一个重点,也是一个难点．难就难在 怎样寻找一个能反映题目全部含义的相等关 系．因此,突破这一难点的关键是学会寻找相 等关系,那么怎样寻找相等关系呢?现结合实例 介绍三条途径,供同学们学习时参考． 途径之一:根据题中的关键语句来寻找相 等关系
The one-item one-step equation solving application is a key point in the chapter of “one-item one-time equation” and it is also a difficult point. It is difficult to find ways to find an equal relationship that reflects the full meaning of the topic. Therefore, the key to breaking through this difficulty is to learn to find equal relationships. Then how do we find equal relationships? We will introduce three approaches in combination with examples to provide students with reference when learning. One of the approaches: Finding equal relationships based on the key sentences in the question. One column of the one-dimensional equation solving application is a key point in the chapter “One Elementary One-Edition” and it is also a difficult point. It is difficult to find ways to find an equal relationship that reflects the full meaning of the topic. Therefore, the key to breaking through this difficulty is to learn to find equal relationships.
