Question

alguém me ajuda por favor ​

Answer 1

Explicação passo-a-passo:

$\frac{x}{4} + \frac{2x}{ 3} \leqslant \frac{5}{6}$

$12( \frac{x}{4} + \frac{2x}{3} ) \leqslant 12 \times \frac{5}{6}$

$12 \times \frac{x}{4} + 12 \times \frac{2x}{ 3} \leqslant 2 \times 5$

$3x + 4 \times 2x \leqslant 10$

$3x + 8x \leqslant 10$

$11x \leqslant 10$

$x \leqslant \frac{10}{11}$

B)

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

$x + 3(x - 1) < 12$

$x + 3x - 3 < 12$

$4x - 3 < 12$

$4x < 12 + 3$

$4x < 15$

$x < \frac{15}{4}$
