人们对方程的研究有悠久的历史,方程是重要的数学基本概念,它随着实践需要而产生,并且具有极其广泛的应用,从数学学科本身看,方程是代数学的核心内容。从代数中关于方程的分类看,一元一次方程是最简单的代数方程,也是所有代数方程的基础,在讨论一元一次方程的解法时,要让学生了解解方程的基本目标(使方程逐步转化为x=a的形式),理解解一元一次方程的一 People have a long history of studying equations. Equations are important basic concepts of mathematics. They are produced with practical needs and have extremely wide applications. From the perspective of mathematics itself, equations are the core content of algebra. From the perspective of the classification of equations in algebra, the one-dimensional first-order equation is the simplest algebraic equation and the foundation of all algebraic equations. When discussing the solution of the one-ary-one equation, students should be made aware of the basic goal of solving the equation (the equation is gradually transformed into The form of x=a)
