Answer 1

Resposta:

$5(x - 6) < - 45 \\ \\ 5x - 30 < - 45 \\ \\ 5x < - 45 + 30 \\ \\ 5x < - 15 \\ \\ x < - \dfrac{15}{5} \\ \\ \LARGE \boxed{\: \green{ x < \bf- 3}}$

$\dfrac{3x}{2} + \dfrac{x}{3} \leqslant 2 \\ \\ \frac{3 \times 3x + 2 \times x \leqslant 2}{6} \\ \\ 9x + 2x \leqslant 2 \\ \\ 11x \leqslant 2 \\ \\ \LARGE \boxed{\green{ x \leqslant \bf\dfrac{2}{11} }} \\ \\ \LARGE \boxed{ \blue{ \underline{ \bf Bons \: Estudos!}}}$
