Question

qual resultado da equação 12 x - 9 = 3 x - 12

Answer 1

✅ Após resolver a equação concluímos que o valor de "X" é:

              $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf x = -\frac{1}{3}\:\:\:}}\end{gathered} }$

Resolvendo equação do primeiro grau:

      $\Large\displaystyle\begin{gathered} 12x - 9 = 3x - 12\end{gathered}$

   $\Large\displaystyle\begin{gathered} 12x - 3x = -12 + 9\end{gathered}$

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

                    $\Large\displaystyle\begin{gathered} x = -\frac{3}{9}\end{gathered}$

                    $\Large\displaystyle\begin{gathered} x = -\frac{1}{3}\end{gathered}$

✅ Portanto:

                    $\Large\displaystyle\begin{gathered} x = -\frac{1}{3}\end{gathered}$

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