二元一次方程组的相关知识及其应用,是中学数学的重要内容之一,对培养学生的分析问题、解决问题的能力和创新意识都具有重要的作用.二元一次方程组是一元一次方程内容的深化和发展,是方程组内容的开端,它是学习二元二次方程组及其他方程组必备的基础知识.二元一次方程组既是平面几何中计算和证明的一种重要的代数解法,也是确定一次函数和只含有两个字母系数的二次函数解析式的一种重要方法,更是研究两直线位置关系的一种重要手段.二元一次方程组中渗透的数学建模思想与化归思想以及消元法,也是学生今后
It is one of the important contents of mathematics in middle school and it plays an important role in cultivating students’ analytical ability, problem-solving ability and innovative consciousness.Binary Equations is a unitary equation The deepening and development of the content is the beginning of the content of the system of equations, which is the necessary basic knowledge for learning the system of binary quadratic equations and other equations.Binary equation is not only an important algebra which is calculated and proved in plane geometry The solution is also an important method to determine the linear function and analytic formula of quadratic function containing only two alphabetic coefficients, and it is also an important method to study the positional relationship between two lines. The idea of mathematical modeling of infiltration in binary linear equations With the return of thought and the elimination of law, but also the future students
