Pesso desculpa por serem tantas não levem a mal so que eu nao sei nada disto

Answer 1

A) 4 -3x > -2 =
-3x>-6 .(-1) =
X<6/3 = x<2

B) 2x+1<3x+2=
-x< 2-1=
-x< 1 .(-1)=
=X> -1

C) 5x-4 ≥12=
5x ≥ 16 =
=X ≥ 16/5

D) 12x+5 ≤ -4=
12x ≤ -9 =
=X ≤ -9/12

E)-7x-50 ≤ -1=
-7x ≤ 49 .(-1)
7x ≥ -49=
= x ≥ -49/7 = x≥ -7

F)-6x+70> -2=
-6x> -72 .(-1)
6x<72=
=X<12

G) x-8<-1=
=X<7

H)-9+x<4=
=X<13

I)2-3x>x+14=
-4x> 12 .(-1)
4x< 12=
=X<3

J)3-x<5+x=
-2x<2 .(-1)
2x>-2=
=X>-1

K)2x<15=
= x< 15/2

L) x:7>-2=
X> 7 . -2=
=X> 14

M)-6x ≥ -20 .(-1)
6x ≤ 20 =
=X ≤ 20/6

N) 2x-18>4x-38=
2x-4x> +18-38=
-2x>-20 -.(-1)
2x<20=
=X<10

O) 2x+1 ≤ x+6=
=X ≤ 5
