Answer 1

$\large\boxed{\begin{array}{l} \sf{2x + 14 = 50} \\ \sf{2x = 50 - 14} \\ \sf{2x = 36} \\ \sf{x = \dfrac{36}{2} } \\ \huge\boxed{\boxed{\boxed{\boxed{\sf{x = 18}}}}}\end{array}}$

Answer 2

✅ Após resolver os cálculos, concluímos que a idade de Marcos é:

           $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf 18 \:\:anos\:\:\:}}\end{gathered} }$

Montando e resolvendo equação do primeiro grau:

      $\Large\displaystyle\begin{gathered}\tt 2x + 14 = 50\end{gathered}$

                  $\Large\displaystyle\begin{gathered}\tt 2x = 50 - 14\end{gathered}$

                  $\Large\displaystyle\begin{gathered}\tt 2x = 36\end{gathered}$

                    $\Large\displaystyle\begin{gathered}\tt x = \frac{36}{2} \end{gathered}$

                    $\Large\displaystyle\begin{gathered}\tt x = 18\end{gathered}$

✅ Portanto, o valor de "x" é:

                    $\Large\displaystyle\begin{gathered}\tt x = 18\end{gathered}$
