Question

4x-2(3-x)≤16-8x

(x-1)/2+x/5≥x+3

5(2-3x)+10x<4x-12

15-10x>20

Answer 1

Respuesta:

4x-2(3-x)≤16-8x

4x - 6 + 2x ≤ 16 - 8x

4x + 2x + 8x ≤ 16 + 6

14x ≤ 22

x ≤ 22/14

x ≤ 11/7

(-∞  ; 11/7]

(x-1)/2+x/5≥x+3

{5(x -1) + 2(x)}/10 ≥ x + 3

{5x - 5 + 2x}/10 ≥ x + 3

7x - 5 ≥ 10(x + 3)

7x - 5  ≥ 10x + 30

7x - 10x ≥ 30 + 5

-3x ≥ 35

x ≤ -35/3

x ≤ -11.67

(-∞  ; -35/3]

 

5(2-3x)+10x<4x-12

10 - 15x + 10x < 4x - 12

-15x + 10x - 4x < -12 - 10

-9x < -22

x > -22/-9

x > 22/9

(22/9 ; +∞)

15-10x>20

-10x > 20 - 15

-10x > 5

x < 5/-10

x < -1/2

(-∞ ; -1/2)
