在学习不等式(组)时,我们常常会遇到含有参数的不等式(组)问题.这类问题的解答,对思维有较高的要求,特别是不等式(组)中参数的“取等”问题,常常困扰着大家.为了帮助同学们掌握这类问题的解决方法,我们对这类问题进行分类例析.一、不等式(组)的整数解问题例1已知关于x的不等式4x-a≤0只有4个正整数解,求a的取值范围.分析:由4x-a≤0可得x≤a/4,因为此不等式只有4个正整数解.所以这4个正整 When learning inequality (group), we often encounter the problem of inequality (group) with parameters. The solution of such problems has higher requirements on thinking, especially the inequality (group) In order to help students master the solution to this kind of problem, we classify this kind of problem.Animal Solution of Inequality (Group) Problem 1 Inequality about x is known 4x- a ≤ 0 only 4 positive integer solution, find the value of A. Analysis: 4x-a ≤ 0 available x ≤ a / 4, because this inequality has only 4 positive integer solution. So these four positive integer
