6300-60x=(100-x)×70怎么解
6300-60x=(100-x)×70
630-6x=(100-x)×7
630-6x=700-7x
7x-6x=700-630
x=70

6300-60x=(100-x)×70
6300-60x=7000-70x
70x-60x=7000-6300
10x=700
x=70

6300-60x=(100-x)×70
6300-60x=7000-70x
-60x+70x=7000-6300
10x=700
x=70

633-60X=7000-70X
6300-7000=70X-60X
-700=10X
X=-70

6300-60X=7000-70X
10X=700
X=70
