x+y=60 e x-y= 12​

Answer 1

$\LARGE\displaystyle{}\begin{cases}x + y = 60 \\ \\ x - y = 12\end{cases} \\\\ \LARGE\displaystyle{}\begin{cases} x + y = 60 \\ \\ x = 12 + y\end{cases} \\\\ \LARGE\displaystyle{}12 + y + y = 60 \\\\ \LARGE\displaystyle{}y = 24 \\\\ \LARGE\displaystyle{}x = 12 + 24 \\\\ \LARGE\displaystyle{}x = 36 \\\\ \LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{ \left(x,y\right) =\left(24,36\right) }}}\end{gathered} }$

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