Question

2x - 6= 5x + 12, qual o resultado?

Answer 1

$\Large\displaystyle\begin{gathered} \sf{ 2x-6=5x+12} \end{gathered}$

$\Large\displaystyle\begin{gathered} \sf{2x-5x=12+6 } \end{gathered}$

$\Large\displaystyle\begin{gathered} \sf{-3x=18 } \end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \sf{ x=-\frac{18}{3}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\sf{x=-6}} } \end{gathered} }$

Answer 2

✅ Após resolver a equação do primeiro grau, concluímos que seu conjunto solução  é:

          $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf S = \{-6\}\:\:\:}}\end{gathered} }$

Resolvendo equação do primeiro grau:

          $\Large\displaystyle\begin{gathered}\tt 2x - 6 = 5x + 12\end{gathered}$

       $\Large\displaystyle\begin{gathered}\tt 2x - 5x = 12 + 6\end{gathered}$

              $\Large\displaystyle\begin{gathered}\tt -3x = 18\end{gathered}$

                     $\Large\displaystyle\begin{gathered}\tt x = -\frac{18}{3}\end{gathered}$

                     $\Large\displaystyle\begin{gathered}\tt x = -6\end{gathered}$

✅ Portanto, o conjunto solução é:

                    $\Large\displaystyle\begin{gathered}\tt S = \{-6\}\end{gathered}$
