Question

Determine valor de x
7( x-2)= 5 (x +3)​

Answer 1

Explicação passo-a-passo:

7( x-2)= 5 (x +3)

7x-14=5x+15

7x-2x=15+14

2x=29

x=29/2

Answer 2

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

                 $\Large\displaystyle\begin{gathered}\tt x = \frac{29}{2} \end{gathered}$

Resolvendo equação do primeiro grau:

      $\Large\displaystyle\begin{gathered}\tt 7(x - 2) = 5(x + 3)\end{gathered}$

       $\Large\displaystyle\begin{gathered}\tt 7x - 14 = 5x + 15\end{gathered}$

       $\Large\displaystyle\begin{gathered}\tt 7x - 5x = 15 + 14\end{gathered}$

                  $\Large\displaystyle\begin{gathered}\tt 2x = 29\end{gathered}$

                    $\Large\displaystyle\begin{gathered}\tt x = \frac{29}{2} \end{gathered}$

✅ Portanto, o valor de "x" é:

                    $\Large\displaystyle\begin{gathered}\tt x = \frac{29}{2} \end{gathered}$
