二元一次方程组是代数中的重要内容，同学们必须认真学好．那么，我们怎样学习二元一次方程组呢？一、正确理解二元一次方程组和二元一次方程组解的概念首先，掌握二元一次方程及其解的概念是学习二元一次方程组的基础．含有两个未知数且未知数的次数都是一次的方程叫做二元一 The binary system of primary equations is an important part of algebra. Students must carefully study it. So how do we learn binary equations? First, the correct understanding of binary first order equations and the concept of binary first order equations solution First of all, to grasp the concept of binary first order equations and solutions is the basis for learning binary equations. An equation that contains two unknowns and whose number of times is unknown is called a binary one.
