ME AJUDEM POR FAVOR!​

Answer 1

$\LARGE\displaystyle{}\begin{cases}x + y = 4 \\ \\ 3x + 2y = 6\end{cases} \\\\ \LARGE\displaystyle{}\begin{cases}x = 4 - y \\ \\ 3x + 2y = 6\end{cases} \\\\ \LARGE\displaystyle{}3\left(4 - y\right) + 2y = 6 \\ \LARGE\displaystyle{}y = 6 \\\\ \LARGE\displaystyle{}x = 4 - 6 \\ \\ \LARGE\displaystyle{}x = - 2 \\ \\ \LARGE\displaystyle\text{ \begin{gathered} \underline{\boxed{\boldsymbol{\left(x,y\right) = \left( - 2,6\right) }}}\end{gathered} }$

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

Answer 2

Resposta:

Explicação passo-a-passo:

x+y=4 x(-2)

3x+2y=6

__________

-2x-2y=-8
