初学解一元一次方程时,常常出现这样那样的错误,常见的有以下几种: 1.把方程连等例1解方程3x+12=0. 错解:3x+12=0=-12=-4. 剖析:方程的变形是同解变
When beginners solve a one-time equation, errors like this often occur. The common ones are the following: 1. Join the equations to solve equation 3x+12=0. False solutions: 3x+12=0=-12=- 4. Analysis: The deformation of the equation is the same solution
