Answer 1

$\Large\mathsf\displaystyle{}17 - 3\left( - 8 + 5\cdot2\right) + 4\left(9 - 3\cdot2\right) \\ \Large\mathsf\displaystyle{}17 - 3\left( - 8 + 10\right) + 4\left(9 - 3\cdot2\right) \\ \Large\mathsf\displaystyle{}17 - 3\left( - 8 + 10\right) + 4\left(9 - 6\right) \\ \Large\mathsf\displaystyle{}17 - 3\cdot2 + 4\left(9 - 6\right) \\ \Large\mathsf\displaystyle{}17 - 3\cdot2 + 4\cdot3 \\ \Large\mathsf\displaystyle{}17 - 6 + 4\cdot3 \\ \Large\mathsf\displaystyle{}17 - 6 + 12 \\ \Large\mathsf\displaystyle{}29 - 6 \\\Large\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ 23 }}}\end{gathered} }$

$\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{{ \red{Bons}} \blue{\:Estudos}}}}\end{gathered} }$
