列方程是解决实际问题的重要途径之一,正确地找出等量关系则是开启方程大门的一把“金钥匙”。下面通过对列方程解决应用题的典型错例的分析,以及正确解法的点拨,以便让同学们从中吸取教训,并能够从中有所感悟,正确地找到等量关系,进而达到顺利解决问题的目的。 Column equation is one of the important ways to solve practical problems. To correctly find the equivalent relation is a “golden key” that opens the door to the equation. The following through the column equation to solve the typical application of the wrong example analysis, as well as the correct solution to the call, in order to allow students to learn from it, and be able to find the correct understanding of the same amount of relations, so as to achieve the purpose of a smooth solution to the problem .
