Question

resposta da equação 2 a + 4 = - 6​

Answer 1

2a + 4 = -6

2a = -6 -4

2a= -10

a = -10/2

a= -5

Answer 2

✅ Após resolver a equação do primeiro grau, concluímos que o valor de "a" é:

             $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf a = -5\:\:\:}}\end{gathered} }$

Resolvendo equação do primeiro grau:

      $\Large\displaystyle\begin{gathered}\tt 2a + 4 = -6\end{gathered}$

               $\Large\displaystyle\begin{gathered}\tt 2a = -6 - 4\end{gathered}$

               $\Large\displaystyle\begin{gathered}\tt 2a = -10\end{gathered}$

                 $\Large\displaystyle\begin{gathered}\tt a = -\frac{10}{2} \end{gathered}$

                 $\Large\displaystyle\begin{gathered}\tt a = -5\end{gathered}$

✅ Portanto, o valor de "a" é:

                 $\Large\displaystyle\begin{gathered}\tt a = -5\end{gathered}$
