一、准确掌握概念只含有一个未知数,并且未知数的次数为1,系数不等于0的不等式叫做一元一次不等式,在这里要把握三个要点:未知数的次数、个数及系数,三者缺一不可。二、牢记标准形式一元一次不等式的标准形式是ax+b>0或ax+b<0(a≠0). First, the concept of accurate grasp only contains an unknown number, and the number of unknowns is 1, the inequality of coefficient is not equal to 0 is called a one-time inequality, here we must grasp three main points: the number of unknowns, the number and coefficient, three are indispensable . Second, keep in mind that the standard form of the one-time inequalities in the standard form is ax+b>0 or ax+b<0 (a≠0).
