Question

3 (x - 1) - 2x ≤ 13

me ajudem isso é de operação inversa ​

Answer 1

$\Large\mathsf\displaystyle{}3\left( x - 1\right) - 2x \leqslant 13 \\ \Large\mathsf\displaystyle{}3x - 3 - 2x \leqslant 13 \\ \Large\mathsf\displaystyle{}x - 3 \leqslant 13 \\\Large\mathsf\displaystyle{}x \leqslant 13 + 3 \\\Large\mathsf\displaystyle{}\Large\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ x \leqslant 16 }}}\end{gathered} }$

$\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{{ \red{Bons}} \blue{\:Estudos}}}}\end{gathered} }$
