✅ Após resolver os cálculos, concluímos que o valor do número procurado é:
[tex]\Large\displaystyle\text{$\begin{gathered}\boxed{\boxed{\:\:\:\bf x = 8\:\:\:}}\end{gathered}$}[/tex]
Montando e resolvendo equação do primeiro grau:
[tex]\Large\displaystyle\text{$\begin{gathered} x + x + 1 = 17\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered} x + x = 17 - 1\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered} 2x = 16\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered} x = \frac{16}{2}\end{gathered}$}[/tex]
[tex]\Large\displaystyle\text{$\begin{gathered} x = 8\end{gathered}$}[/tex]
✅ Portanto, o número procurado é:
[tex]\Large\displaystyle\text{$\begin{gathered} x = 8\end{gathered}$}[/tex]
[tex]\LARGE\displaystyle\text{$\begin{gathered} \underline{\boxed{\boldsymbol{\:\:\:Bons \:estudos!!\:\:\:Boa\: sorte!!\:\:\:}}}\end{gathered}$}[/tex]
