分段来解1，当x大于4时原方程可化为x+2+x-4=8so x=52，当x小于4大于-2时原方程可化为x+2-x+4=8不成立，无解3，当x小于-2时原式可化为-x-2-x+4=8so x=-3所以原方程有两个解，分别为5和-3

展开全部6÷7x-8=4解方程式过程如下：6÷7x-8=4解：6÷7x=4+86÷7x=126=84xx=1/14所以6÷7x-8=4解方程式最后的结果是x=1/14。扩展资料：解方程的几种方法：1、估算法：刚学解方程时的入门方法。直接估计方程的解，然后代入原方程验证。2、合并同类项：使方程变形为单项式。3、移项：可以将含未知数的项移到左边，常数项移到右边。4、应用等式的性质进行解方程。已赞过已踩过你对这个回答的评价是？评论
