50+0.4x=0.6x怎么解50+0.4x=0.6x怎么解50+0.4x=0.6x怎么解50=0.6x-0.4x=0.2xx=50/0.2=25050+0.4x=0.6x50=0.6x-0.4x50

50+0.4x=0.6x怎么解
50+0.4x=0.6x怎么解

50+0.4x=0.6x怎么解
50=0.6x-0.4x=0.2x
x=50/0.2=250

50+0.4x=0.6x
50=0.6x-0.4x
50=0.2x
x=50/0.2
x=250

先移项,将0.4x移到等号右边,变成负的,即50=0.6x-0.4x
0.2x=50解得x=250

50+0.4x=0.6x
50=0.2x
50=0.2x
0.2x=50
x=50/0.2
x=250
