8 - 2(5-х)>1         2(2х-5)+4≥3х            4(2х-3)≤3х-2           9х-2(х-4)<1  
8-2*5+2x>1         2*2х-2*5+4-3х≥0       4*2х-4*3≤3х-2        9x-2x+8<1
2x>1-8+10           4х-3х≥10-4                8х-3х≤4-2               7x<1-8
x>3/2                    х≥6                            х≤2/5                       x<-7/7
x>1.5                                                      х≤0,4                       x<-1
x∈(1.5;+∞)            х∈[6;+∞)                    х∈(-∞;0,4]                x∈(-∞;-1)
