Respuesta:
En la primera es y = - 8
X = 16
En la segunda es y = 8
X = 12
Explicación paso a paso:
2x + 2y = 16
4x + 2y = 26
__________
(-2) - 4x - 4y = - 32
4x + 2y = 16
______________
2y = - 16
Y = - 8
2x + 2(-8) =16
2x - 16 = 16
2x = 16 + 16
2
X + y = 20
10x + 4y = 152
___________
(-10) - 10x - 10y = - 200
____________________
-6y = - 48
y = 8
Reemplazamos
X + 8 = 20
X = 20-8
X= 12
10x + (4x8) =152
10x + 32= 152
10x = 120
