对于方程或方程组,当未知数的个数,多于方程的个数时,一般来说,方程(组)的解数不确定,有无穷组解。我们把这种方程或方程组,叫做不定方程或不定方程组。本文里,将讨论几种中学里常见的特殊不定方程为整数解的求法。 中学里常见的不定方程,是二元一次不定 For an equation or a system of equations, when the number of unknowns is more than the number of equations, in general, the number of solutions of equations (groups) is indefinite, and there are infinitely many solutions. We call this equation or set of equations an indefinite or indefinite equation. In this article, we will discuss how to solve the problem of integer solutions for some special indefinite equations in middle schools. The indefinite equation that is common in middle school is an indefinite binary
