(1)2-(3x-5)=2x怎么解这道方程
3-2(0.2x+1)=五分之一x
10+2(x-1/2)=7(x-2)
5x-[1-(3x+2x)]=7
5-6(5/6x-1/2)=2(x-3/4)
5x+2(1-3x)=3(2-1/2x)
2-3x=5

(1)2-(3x-5)=2x怎么解这道方程3-2(0.2x+1)=五分之一x10+2(x-1/2)=7(x-2)5x-[1-(3x+2x)]=75-6(5/6x-1/2)=2(x-3/4)5x+2(1-3x)=3(2-1/2x)2-3x=5
2-(3x-5)=2x
2-3x+5=2X
-3X-2X=-2-5
-5X=-7
X=-7/-5

原式等于2-3x+5=2x,7=5x,解得x=7/5

2-(3x-5)=2x
2-3x+5=2X
-3X-2X=-2-5
-5X=-7
X=-7/-5

x=7/5

2-3x+5=2x
2+5=2x+3x
7=5x
x=7/5
