Question

g) (2x + 3) – (4 – 3x) ≤ 7 – 4 (-5 – 3x)

Answer 1

Resposta:

x ≥ - 4

Explicação passo-a-passo:

g) (2x + 3) – (4 – 3x) ≤ 7 – 4 (-5 – 3x)

2x + 3 - 4 + 3x ≤ 7 - (- 20 - 12x)

2x + 3 - 4 + 3x ≤ 7 + 20 + 12x

5x - 1 ≤ 27 + 12x

5x - 12x ≤ 27 + 1

- 7x ≤ 28

- x ≤ 28/7

- x ≤ 4

- 4 ≤ x

x ≥ - 4
