Answer 2

Respuesta:

- 8x - 5x ≤ 12 - 4

- 13x ≤ 8

x = - 13 / 8

x = - 1.625

Explicación paso a paso:

- 13 + 4 = 8.125 + 12

- 9 ≤ 20.125

- 5x + 2 ≤ 1+ 2

- 5x - 2x ≤ 1 - 2

- 7x ≤ - 1

x = - 1 / - 7

x = 0.14285

- 0.71425 + 2 ≤ 1 + 0.2857

1.28575 ≤ 1.2857

- 4 ≤ 3x + 1 < 8

- 3x ≤8 + 4 - 1

- 3x ≤ 11

x = 11 / - 3

x = - 3.66666

- 4≤ - 11 + 1 < 8

- 4 ≤- 10 < 8
