Question

解不等式1/2+2x/3≤ -x/2 +5/3 1/2(x+3)＜2 x+2/2＞x+3/3

x-3(x-2)≥4 1+2x/3＞ x-1

Answer 1

1/2+2x/3≤ -x/2 +5/3
3+4x<=-3x+10
7x<=7
x<=1
1/2(x+3)＜2
(1-4x-12)/2(x+3)<0
(4x+11)/(x+3)<0
-3<x<-11/4
x+2/2＞x+3/3
3(x+2)＞2(x+3)
3x+6＞2x+6
x＞0
x-3(x-2)≥4
x-3x+6>=4
2x<=2
x<=1
1+2x/3＞ x-1

1+2x＞3(x-1)

1+2x＞3x-3

-x＞-4

x＜4

希望能帮到你！

Answer 2

1/2+2x/3≤ -x/2+5/3
3+4x≤-3x+10
7x≤7
x≤ 1

1/2(x+3)＜2
x+3＜4
x＜1

x+2/2＞x+3/3
3(x+2)＞2(x+3)
3x+6＞2x+6
x＞0

‍
x-3(x-2)≥4

x-3x+6≥4

-2x≥-2

x≤ 1

1+2x/3＞ x-1

1+2x＞3(x-1)

1+2x＞3x-3

-x＞-4

x＜4
