知识展台一元一次方程的解答是有着一定的套路的,我们不妨将其归纳为以下的方法和步骤。1.移项:把含有未知数的项都移到方程的一边,其他项都移到方程的另一边;移项要变号2.合并同类项:把方程化成ax=b(a≠0)的形式;3.去括号:先去小括号,再去中括号,最后去大括号;(记住如括号外有减号的话一定要变号)4.去分母:在方程两边都乘以各分母的最小公倍数; Knowledge Booth a one-time equation solution is a certain set of routines, we may wish to summarize it as the following methods and steps. 1. Move items: Move items with unknowns to one side of the equation and move items to the other side of the equation. Move item to be variable 2. Merge items of the same type: Equate ax = b (a ≠ 0) Form; 3 to the parentheses: go to parentheses, go to the brackets and finally to the curly braces; (remember that if the minus sign except the brackets must be changed sign) 4 to the denominator: multiplied by the denominator on both sides of the equation The least common multiple of
