30÷(x-4)=5,x-4=30/5,x-4=6,x=6+4,x=10哦。![](https://s.bdstatic.com/common/openjs/emoticon/img/face_55.png)

亲亲,30➗(x-4)=5这个方程的解法使用到了移项哦,移项是把方程两边都加上同一个数或同一个整式,就相当于把方程中的某些项改变符号后,从方程的一边移到另一边,这样的变形叫做移项。方程的移项口诀是:已知未知要分离,分离方法就是移,加减移项要变号,乘除移了要颠倒哦。![](https://s.bdstatic.com/common/openjs/emoticon/img/face_55.png)
