有些数学题从表面上看并不具有方程组的特征,但可以根据其基本特征构造出二元一次方程组来解决问题.下面一起来看看吧!一、利用非负数的性质
Some math problems do not have the characteristics of equations on the surface, but can be based on their basic characteristics to construct a binary linear equations to solve the problem. Let's have a look! First, the use of non-negative nature
