在初中数学学习过程中,同学们有时会遇到一些求解三元一次不定方程问题.该问题有这样两种常见情形:一是利用已知的两个三元一次不定方程求值,二是构造两个三元一次不定方程解应用题.无论哪一种情形,解题关键都在于把三元中的任意两元选定为未知元,剩下的一个当作已知元,从而将两个三元一次方程转化为二元一次 In the process of junior high school mathematics learning, students sometimes encounter some problems of solving ternary indefinite equation.There are two common cases of this problem: one is to use the known two ternary indefinite equation to evaluate, the other is to construct In any case, the key to solve the problem is to select any two yuan in the ternary as the unknown element and the remaining one as the known element, so that the two The ternary equation is converted to binary once
