Question

$- x - 11 > 3 \\ 4 - 3x > x + 6 \\ 3x + 8 < 6 + 5x \\ 4 \times - 2 < 6x + 8$
​

Answer 1

Resposta:

$- x - 11 > 3 \\ \\ - x > 3 + 11 \\ \\ - x > 14 \\ \\ x < - 14$

$4 - 3x > x + 6 \\ \\ - 3x - x > 6 - 4 \\ \\ - 4x > 2 \\ \\ x < - \frac{1}{2}$

$3x + 8 < 6 + 5x \\ \\ 3x - 5x < 6 - 8 \\ \\ - 2x < - 2 \\ \\ x > 1$

$4 \times - 2 < 6x + 8 \\ \\ - 8 < 6x + 8 \\ \\ - 6x < 16 \\ \\ 6x > - 16 \\ \\ \\ \\ x > - \frac{8}{3} .$
