1.
From the application of facility equation to the application of binary linear equation group, distinct teaching content, versus the uniform students, the author used the same mathematical situations to carry out the teaching of 搈athematical situation and posing problems? As the development of cooperative learning between teachers and students, students?problem intention gradually came into being.
在讲授从“简易方程的应用”到“二元一次方程组的应用”过程中,不同的教学内容,对相同的学生,用相同的数学情境,进行“情境—问题”教学,随着师生合作学习的深入,学生的问题意识也在逐渐形成、不断强化。

5) binary linear equations
二元线性方程
6) binary quadratic equations
二元二次方程
1.
This paper constructs iterative algorithm of binary quadratic equations by using extract roots formula of quadratic equation,explains practical application of iterative algorithm of binary quadratic equations by drawing solving process of binary quadratic equations.
利用一元二次方程的求根公式构造二元二次方程组的迭代算法,通过图解二元二次方程组的解来说明迭代算法在实践中的应用。
补充资料：二元一次方程
有两种不同字母构成的方程，一般有两条二元一次方程才能解出未知数的解,也就是二元一次方程组.二元一次方程组有代入消元法,加减消元法.
例:
1)x-y=3
2)3x-8y=14
3)x=y+3
代入得
３×（y+３)-8y=14
y=-1
所以x=2
这个二元一次方程组的解
x=2
y=-1
