一元一次方程是方程中的最基本、最简单的方程,解一元一次方程就是运用等式的基本性质对方程进行变形化简。由于学生刚开始学习一元一次方程,往往由于忽略等式的性质或某些运算法则而导致出错。现对同学们在解一元一次方程的过程中常出现过的错例进行归类剖析如下:一、错用连等:例1解方程6x-5=2x+3错解:6x-5=2x+3=6x-2x=3+5=4x=8=x=2剖析:解方程时应先移项,再合并同类项,最后
The linear equation is the most basic and simple equation in the equation. To solve a unary linear equation, the equation is transformed using the basic properties of the equation. Because students are just starting to learn a one-dollar equation, they often make mistakes by ignoring the nature of the equation or by some algorithms. Now, we classify the wrong examples that students often encounter in solving the unary equation as follows: First, wrongly connected: Example 1 Solution 6x-5 = 2x + 3 Error Solution: 6x-5 = 2x + 3 = 6x-2x = 3 + 5 = 4x = 8 = x = 2 Anatomy: the equation should be moved first, and then merge the same items, and finally
