Question

ayudaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa porfavorrrrrrrrrrrrrrrrrrrrrrr

Answer 1

Respuesta:

3/4 x + 6 ≤ 12

PRIMERA DESIGUALDAD:

3/4 x ≤ 12 - 6

3/4 x ≤ 6

3x ≤ 4 * 6

3x ≤ 24

x ≤ 24/3

x ≤ 8

SEGUNDA DESIGUALDAD:

(x + 8) / 4 ≥ 2x - 5

(x + 8) / 4 - 5 ≥ 2x

(x + 6 - 20) / 4 ≥ 2x

x + 6 - 20 ≥ 2x * 4

x + 6 - 20 ≥ 8x

6 - 20 ≥ 8x - x

- 14 ≥ 7x

-14/7 ≥ x

- 2 ≥ x
