Respuesta:
4x+2y=-8
3x-2y=22
7x = 14
x = 14/7
x = 2
Reemplazando
4(2) + 2y = -8
8 + 2y = -8
2y = -16
y = -8
3x - 2(-8) = 22
3x + 16 = 22
3x = 6
y = -8 x= 2
Explicación paso a paso:
4x+2y=-8; x= [tex]\frac{-8 -2y }{4}[/tex]
3([tex]\frac{-8 -2y }{4}[/tex]) - 2 y = 22
[tex]\frac{- 24 - 6 y}{4}[/tex]-2 y = 22
-6 - [tex]\frac{3}{2}[/tex] y - 2 y = 22
- [tex]\frac{3}{2}[/tex] y - 2 y = 22 +6
[tex]\frac{-3-4}{2}[/tex]y= 28
[tex]\frac{-7}{2}[/tex] y = 28
7y = - (2) (28)
y= -56 / 7
3x-2(-8)=22
3x= 22 -16
x= 6/3
x= 2
