Question

2x + 5 > - 3× +40
$2x + 5 \geqslant - 3 \times + 40$
​

Answer 1

Olá!!

2x + 5 ≥ -3x + 40 ← Movendo termo

2x + 3x ≥ 40 - 5 ← Calculando

5x ≥ 35 ← Movendo termo

x ≥ 35/5 ← Dividindo

x ≥ 7 ← Resultado

Answer 2

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

            $\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{\:\:\:\bf x\ge 7\:\:\:}}\end{gathered} }$

Resolvendo a inequação do primeiro grau:

        $\Large\displaystyle\begin{gathered} 2x + 5 \ge -3x + 40\end{gathered}$

     $\Large\displaystyle\begin{gathered} 2x + 3x \ge40 - 5\end{gathered}$

               $\Large\displaystyle\begin{gathered} 5x \ge 35\end{gathered}$

                 $\Large\displaystyle\begin{gathered} x \ge \frac{35}{5} \end{gathered}$

                  $\Large\displaystyle\begin{gathered} x \ge 7\end{gathered}$

✅ Portanto, o valor de "x" é:

                  $\Large\displaystyle\begin{gathered} x \ge 7\end{gathered}$
