有些同学对应用题感到困难,其实在列方程解方程的过程中都有些技巧,学习并掌握一些常用的技巧是必需的,这有助于我们正确、迅速地解题,下面看几个分式方程的例子:例1 A、B 两地间的道路,有一部分是上坡路,其余的都是下坡路,骑自行车走下坡路比走上坡路每小时多走6千米,已知骑自行车从 A 地到 B 地需2小时40分,从 B 地回到 A 地可少用 Some students are puzzled by the application of the problem, in fact, in the process of solving the equation equations have some skills, learning and mastering some commonly used skills are necessary, which helps us to solve the problem correctly and quickly, see below a few fractional Examples of equations: Example 1 A, B Road between the two places, some of which are uphill, and the rest are downhill. Walking downhill on a bicycle is 6 km more per hour than walking uphill. It is known to ride bicycles from A to B. It takes 2 hours and 40 minutes for the land to return to place A from B to use less
