Respuesta :
2*y= x - 8, y= 2x - 10
2* (2x-10)= x - 8
2*2x - 2*10= x - 8
4x - 20= x - 8 | +20
4x = x + 20 - 8 = x + 12 | - x
4x - x = 12
3x = 12
x= 12:3
x= 4
y= 2*4 - 10
y= 8 - 10
y= - 2
2* (2x-10)= x - 8
2*2x - 2*10= x - 8
4x - 20= x - 8 | +20
4x = x + 20 - 8 = x + 12 | - x
4x - x = 12
3x = 12
x= 12:3
x= 4
y= 2*4 - 10
y= 8 - 10
y= - 2
