重点难点易混易错点剖析复习重点:等式与不等式(组)是初中代数的主干知识,在中考中常常以基础题目出现,在解答题中往往是以方程、不等式、函数相结合的实际问题,这要求能够准确求H出方程或不等式的解(集),综合运用方程和不等式进行有关计算.复习难点:在解决实际问题中,如何综合运用方程和不等式的知识和方法解决问题,选择合适的方式来表达题目中出现的数量关系.易混易错点:方程、不等式和一次函数相
Key points Difficult to misuse Analysis of the wrong point Focus: Equations and inequalities (group) is the backbone of junior high school algebra knowledge in the examination often appear in the basic topics in the answer questions are often based on equations, inequalities, the combination of the actual function Problem, which requires that we can accurately find the solution of H out of the equation or inequality, and use the equation and inequality to make the calculation.Review difficult: How to solve the problem by combining the knowledge and method of equation and inequality, The right way to express the number of problems in the title. Easy to mix and error points: equations, inequalities and a function of phase
