Question

x -4y = 2
2x +y = 16
ajudem eu <3

Answer 1

x = 4y+2

vamos substituir

2(4y+2)+y = 16

8y+4+y = 16

9y = 12

y = 4/3

vamos substituir novamente

x = 4(4/3)+2

x = (4/1)(4/3)+2

x = (16/3)+2

x = (16/3)+(6/3)

x = 22/3

Answer 2

Bom dia 

x - 4y = 2
2x + y = 16 

x - 4y = 2
8x + 4y = 64 

9x = 66
x = 66/9 = 22/3 

22/3 - 4y = 6/3
4y = 16/3
y = 16/12 = 4/3
