解方程:x-100)÷50-2= (x-100)÷60+5
解方程:x-100)÷50-2= (x-100)÷60+5

解方程:x-100)÷50-2= (x-100)÷60+5
(x-100)÷50-2= (x-100)÷60+5
乘以300得 6(x-100)-600=5(x-100)+1500
x-100-600=1500
x=1500+100+600
x=2200

(x-100)(1/50-1/60)=7
(x-100)(1/300)=7
x-100=2100
x=2200

(x-100)÷50-2= (x-100)÷60+5
(x-100)÷50= (x-100)÷60+7
(x-100)÷50-(x-100)÷60=7
两边同乘以300得:
X-100=2100
X=2200
经检验,X=2200为原方程的解。
