1/2x+1>-3 -2x-4<4x+4 2x+1>3 2-x<1 2(x+1)<3x 3(2x+2)≥4(x-1)+7 x/2+1>x 2/3x≤1/3(x-2)

问题描述:

1/2x+1>-3 -2x-4<4x+4 2x+1>3 2-x<1 2(x+1)<3x 3(2x+2)≥4(x-1)+7 x/2+1>x 2/3x≤1/3(x-2)
3(x+1)<4(x-2)-3 1/6(1-9x)<-7-3/2x
解不等式
(1)1/2x+1>-3 (2)-2x-4<4x+4 (3)2x+1>3 (4)2-x<1 (5)2(x+1)<3x (6)3(2x+2)≥4(x-1)+7 (7) x/2+1>x (8)2/3x≤1/3(x-2) (9)3(x+1)<4(x-2)-3 (10) 1/6(1-9x)<-7-3/2x
解不等式 是分开来的啊

3(x+1)
