Question

X+2y=50 2x+y=55 me ajudem!!!!

Answer 1

X+2y=50
2x+y=55

x= 50 - 2y
y= 55 - 2x

x= 50 - 2.(55-2x)
x= 50 - 110 + 4x
x-4x=
-3x= -60
x= -60/-3
x= 20

y= 55 -2x
y = 55 - 2.20
y= 55-40
y= 15

x+2y=50
20+2.15=50
20+30=50
50=50

Answer 2

Boa dia

x + 2y = 50,
2x + y = 55 

x + 2y = 50 
4x + 2y = 110 

4x - x = 110 - 50 
3x = 60
x = 20 

20 + 2y = 50
2y = 30
y = 30/2 = 15 

S = (20, 15)
