3 2

Answer 1

A) 2-3X>X+14
-3x-x > 14-2
-4x >12 
x<12/-4
x<-3

B)3x+6>0
3x>-6
x>-2

C) -2 (x-1)-6(1-x) >0 
-2x+2-6+6x>0
4x-4>0
4x>4
x>1

D) (X+3)>(-X-1)
x+3>-x-1
x+x>-1-3
2x>-4
x>-2

E)8(X+3)>12(1-X)
8x+24>12-12x
8x+12x>12-24
20x>-12
x>-12/20 simplificando..
x>-3/5

F)5(-X+1)+2(3X-4)>-1
-5x+5+6x-8>-1
x>-1+3
x>2

G)-X+3<2X+5
-x-2x<5-3
-3x<2
x>-2/3
