随着新课程的改革,列方程解应用题也在不断变化,一方面贴近生活,一方面注重培养同学们获取信息、解决实际问题的能力,其中将已知条件以图形或图表的形式给出,是常见的题型之一。下面举几个例子与大家分享。一、图形折叠中找关系图1例1如图1,是一个正方体的展开图,标注了字母“a”的面是正方体的正面,如果正方体相对两个面上的代数式的值相等,求x、y的值。分析:解决本题的关键是根据正方体 With the reform of the new curriculum, the application of column equation solution is also changing, on the one hand, close to life, on the one hand focus on training students to acquire information, the ability to solve practical problems, which will be known conditions given in the form of graphics or charts , Is one of the common questions. Here are some examples to share with you. First, the graph fold to find the relationship Figure 1 Example 1 Figure 1, is a cube of the expansion diagram, marked with the letter “a ” face is the front of the cube, if the cubes relative to both sides of the algebraic values ​​?? are equal, Find x, y value. Analysis: The key to solve this problem is based on the cube
