一、找准等量关系是列方程解应用题的钥匙列方程解应用题的窍门枚不胜举,其中找准等量关系处于核心地位,类似解决价格问题、银行利率问题、溶液浓度问题和工程问题等必须通过找准等量关系才能解决问题.它包括列表分析法、译式分析法、线示分析法、逆推法和图示分析法等.在初中数学中涉及的列方程求解应用题的题型中,前四种方法的使用比较普遍.
First, identify the equivalent relationship is the solution to the column equation key column equation solution to the problem of numerous tips, which identify the relationship between the equivalent at the core, similar to solve the price problem, the bank interest rate problems, solution concentration and engineering Problems, etc. must be found by finding the same amount of relations to solve the problem.It includes list analysis, translation analysis, line analysis, reverse push and graphical analysis, etc. In the junior high school mathematics involved in the column equation to solve the problem Of the questions, the first four methods are more common use.
