一元一次方程是同学们今后学习方程组、不等式的基础,熟练应用相关概念和方法解一元一次方程竞赛题,有利于培养同学们的数学能力和思维品质,下面我们共同探究一元一次方程竞赛题的解法.一、知识储备1,基本概念.(1)一元一次方程:只含有一个未知数(元),且未知数的次数都是1,等号两边都是整式的方程.(2)方程的解:使方程中等号左右两边相等的未知数的值. Unary one-time equation is the basis for students to learn equations and inequalities in the future, skilled application of related concepts and methods to solve the one-dollar one-time equation competition questions, is conducive to cultivating students’ mathematical ability and thinking quality, below we explore one dollar equation competition questions Solution 1. First, the basic concept of a (1) a linear equation: only contains an unknown (yuan), and the number of unknowns are 1, both sides of the equals sign are integral equations. (2) Solution of the equation: Equate the equal sign in the equation with equal unknowns on both sides.
