Question

5×-3+×=2×+9 conta armada de equação

Answer 1

Olá

$\LARGE\tt{}5x - 3 + x = 2x + 9 \\\LARGE\tt{} 6x - 3 = 2x + 9 \\ \LARGE\tt{}6x - 3 - 2x = 9 \\ \LARGE\tt{}6x - 2x = 9 + 3 \\ \LARGE\tt{}4x = 9 + 3 \\ \LARGE\tt{}4x = 12 \\ \\ \LARGE\tt{}x = \dfrac{12}{4} \\ \\ \\ {\large\boxed{\boxed{  { \LARGE \tt x = 3}}}}$

${\large\boxed{\boxed{  { \large \tt BONS \: \: ESTUDOS \: MEU \: ANJO \:\red{\heartsuit} }}}}$

Answer 2

✅ Tendo resolvido a equação do primeiro grau, concluímos que seu conjunto solução é:

                    $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf S = \{3\}\:\:\:}}\end{gathered} }$

Resolvendo equação do primeiro grau:

         $\Large\displaystyle\begin{gathered} 5x - 3 + x = 2x + 9\end{gathered}$

       $\Large\displaystyle\begin{gathered} 5x + x - 2x = 9 + 3\end{gathered}$

                            $\Large\displaystyle\begin{gathered} 4x = 12\end{gathered}$

                               $\Large\displaystyle\begin{gathered} x = \frac{12}{4}\end{gathered}$

                               $\Large\displaystyle\begin{gathered} x = 3\end{gathered}$

✅ Portanto, o conjunto solução é:

                              $\Large\displaystyle\begin{gathered} S = \{3\}\end{gathered}$

$\LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{\:\:\:Bons \:estudos!!\:\:\:Boa\: sorte!!\:\:\:}}}\end{gathered} }$
