Question

解下列不等式，并把它们的解集分别表示在数轴上:1.3x-2x<5 2.x-6>2x 3.x/2>x/3 4.2x-7>5-2x 5.1-3x/2>1-2x

6.x-1/2(4x-1)<2 7.x-1/2+1>x/4
急急急急急急急阿 求各位高手相救阿T T

Answer 1

1.3x-2x<5
x<5
2.x-6>2x
x<-6
3.x/2>x/3
x/2-x/3>0
x>0
4.2x-7>5-2x
4x>12
x>3
5.1-3x/2>1-2x
1/2x>0
x>0
6.x-1/2(4x-1)<2
-x+1/2<2
x>-3/2
7.x-1/2+1>x/4
3/4x>-1/2
x>-2/3
