Answer 1

Hola!

12+x>23-2

x > 21 - 12

x > 9

S = (9, +∞)

x/3>8

x > 8 . 3

x > 24

S = (24, +∞)

x/2>5

x > 10

S = (10, +∞)

x+2/3<2

x < 2 - 2/3

x < 4/3

S= (-∞, 4/3)

x/2<3+6

x < 9 . 2

x < 18

S= (-∞, 18)

2x+x<63

3x < 63

x < 21

S= (-∞, 21)

3x+x>24

4x > 24

x > 6

S = (6, +∞)

x+10+2<=20

x <= 20 -12

x <= 8

S = (-∞, 8]

12+x<=25+2

x <= 27 - 12

x <= 15

S = (-∞, 15]

x/3<2+6

x < 8 . 3

x < 24

S = (-∞, 24)

x/5>3-1

x > 2 . 5

x > 10

S= (10, +∞)

x/2+3<5

x/2 < 5 - 3

x < 2 . 2

x < 4

S = (-∞, 4)

x+4/4<3

x < 3 - 1

x < 2

S = (-∞, 2)

x/6-2>1

x/6 > 1 + 2

x > 3 . 6

x > 18

S = ( 18, +∞)
