列方程(组)解应用题是初中数学的一个重要内容,掌握列方程(组)解应用题的设元方法是解决应用题问题的首要途径.列方程(组)解应用题时,恰当地设元,对寻找等量关系列方程(组)关系极大.下面介绍列方程(组)解应用题设元的四种基本方法.
Solving equations (groups) Solving an application is an important part of junior mathematics. Grasping a parametrization method for solving equations (groups) is the first way to solve the problem of an applied problem. When solving equations (groups), it is appropriate to solve the problem. Set the yuan, for the relationship between the equations (groups) to find the equivalent relationship is extremely large. The following four basic methods for solving equations (groups) solver problems are introduced.
