三元一次方程组比二元一次方程组复杂一些 ,而且也没有一般的解法步骤 ,有些题的解法技巧性很强 ,因此 ,学生在解此类方程组时常感到困难。那么 ,怎样才能掌握好三元一次方程组的解法呢 ?这就需要注意 :1 .解题思想 :“消元”、“转化”的思想 ,即把“三元”转化为“二元”,再? The ternary equations are more complex than the binary ones, and there are no general solution steps. Some questions have very strong solutions. Therefore, students often find it difficult to solve such equations. Then, how can we master the solution of the ternary equations? This requires attention: 1. Problem-solving ideology: The idea of ​​“elimination of the yuan” and “transformation” is to convert “three yuan” into “binary”. again?
