一、一元一次方程计算题错解分析学习一元一次方程的关键是能熟练地求出一元一次方程的解,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,直至解到x=a的形式.但同学们在学习一元一次方程的解法时,往往由于忽视了等式的性质或某些运算法则而导致错解方程.现对常见的错解归类剖析如下:1.去分母时,漏乘不含分母的项或分子忘记加括号
First, a dollar equation analysis of the wrong solution analysis Learning the key to a one-time equation is to be able to formulate a one-time equation solution, the solution of a linear equation is the use of the basic nature of equations to simplify the equation until the solution to x = a.However, when students learn the solution of the linear equation, they often misunderstand the equation because they ignore the nature of the equation or some algorithms.Now the common misdirected classification is as follows: When missing the numerator or denominator, forget the parentheses
