解下列不等式组x-1>3(x+1),(1/3)≤4-(4/3)x (3x-7)÷5<(x-2)÷2,(x/4)-(2x-1)÷12≥(1/6)-(x/3)

问题描述:

解下列不等式组x-1>3(x+1),(1/3)≤4-(4/3)x (3x-7)÷5<(x-2)÷2,(x/4)-(2x-1)÷12≥(1/6)-(x/3)

x-1>3(x+1),.x>3x+3+1,.-2x>4.x<-2
(1/3)≤4-(4/3)x .(4/3)x≤4-1/3.(4/3)x≤11/3.x≤11/4.
(3x-7)÷5<(x-2)÷2.2(3x-7)<5(x-2).6x-14<5x-10.x<4
(x/4)-(2x-1)÷12≥(1/6)-(x/3)
3x-(2x-1)≥2-4x
3x-2x+1≥2-4x
5x+1≥2
5x≥1
x≥1/5
