1.{x-1/2小于或等于2x-1/5
-5x+1>3(x-3)
2.2减x/3加x-1/2>1减x+4/6
是解一元一次不等式和不等式组

1.{x-1/2小于或等于2x-1/5 -5x+1>3(x-3) 2.2减x/3加x-1/2>1减x+4/61.{x-1/2小于或等于2x-1/5 -5x+1>3(x-3) 2.2减x/3加x-1/2>1减x+4/6是解一元一次不等式和不等式组
1.x-1/2小于或等于2x-1/5 可化为:
5(x-1)<=2(2x-1)
5x-5<=4x-2
x<=3
-5x+1>3(x-3) 可化为:
-5x+1>3x-9
-8x>-10
x>5/4
所以:5/4<x<=3
2.2减x/3加x-1/2>1减x+4/6 可化为:
12-2x+3x-3>6-6x+4
7x>1
x>1/7

1.-3/102.x>1/10

妈妈啊!!!!呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜呜
