Resposta:

$\Large \: 5 - \frac{1}{3} - \left( - \frac{1}{6} + \frac{3}{4} \right) = \\ \\ \Large = 5 - \frac{1}{3} - \left( \frac{ - 4 \times 1 + 6 \times 3}{24} \right) \\ \\\Large = 5 - \frac{1}{3} - \left( \frac{ - 4 + 18}{24} \right) \\ \\ \Large = 5 - \frac{1}{3} - \left( \frac{ 14 \div 2}{24 \div 2} \right) \\ \\\Large = 5 - \frac{1}{3} - \left( \frac{7}{12} \right) \\ \\ \Large = 5 - \frac{1}{3} - \frac{7}{12} \\ \\ \Large = \frac{12 \times 5 - 4 \times 1 - 1 \times 7}{12} \\ \\ \Large = \frac{60 - 4 - 7}{12} \\ \\ \Large = \frac{60 - 11}{12} \\ \\ = \Large \boxed{ \green{ \bf \dfrac{49}{12} }} \\ \\ \Large \boxed{ \underline{ \blue{ \bf \: Bons \: Estudos!} \: 15/05/2021}}$
