推荐回答（5个）

回答1：

闲的没事是不是！以你的题目x应该是整数，否则你的通项自相矛盾。因为x-1和x如果不是整数，你分母究竟是什么规律？？？

但是没有一个整数x能满足这个方程。最接近是x=26时，从26/1,26/2到26/26的和最接近100

回答2：

先未知数和已知数分别移到一边，变为
6x-4x=15+60，
进一步为：2x=75
最后：x=75/2

回答3：

4x+15=6x-60
15=2x-60
75=2x
x=75/2=37.5

回答4：

4X+15=6X-60
2X=75
X=37.5

回答5：

1. 4x+15=6x-60 2.4x+15=6x-60
15=2x-60 6x-4x=60+15
60+15=2x 2x=75
75=2x X=37.5
x=37.5
