hartnn · Answer

-3x + y = 0

add 3x on both sides,
what u get?

So it should look like this -3x+y-3x=0-3x?
@hartnn  I am very sorry my WiFi messed up so I didn't see your reply... I'm really sorry

hartnn · Answer

hey no problem :)

and we had to add 3x, not subtract.

-3y + y + 3y = 0 +3y


so what does y= .. .

abbycross167 · Answer

oh ok..
y=0?

hartnn · Answer

i meant,

-3x + y + 3x = 0 + 3x

so 
y= 3x

now we "substitute" this in 2nd equation,

hartnn · Answer

3x -y = -12

substitute y= 3x in this
