列方程解应用题是初中数学的重点和难点,要列出方程,关键是要找出题中的等量关系.为解决这类问题,我向大家介绍一种方法——列表法.利用列表法我们很容易将题中的已知量与未知量之间的关系表示出来.举例如下.
The application of equations in solving equations is the key and difficult point in junior mathematics. To list the equations, the key is to find the equal relations in the questions. To solve this kind of problem, I will introduce a method—list method. We can easily express the relationship between the known quantity and the unknown quantity in the problem. Examples are as follows.
