3 x -11 = y
x - 3 y = 9 ??
I can not draw the lines but
3 x - 11 = y
3 x - 9 y = 27
------------------------ subtract
-11 + 9 y = y - 27
8 y = -16
y = -2
then
3 x - 11 = y
3 x - 11 = -2
3 x =9
x =3
=================
check
===================
x - 3 y = 9 ?
3 - 3(-2) = ?
3 + 6 = 9 sure enough
Solve the simultaneous equation by graphical method

3 x -11 = y
what does that line look like?
if x = 0, y =-11 so mark (0,11)
if y = 0, x = 11/3 so mark (11/3 , 0)
etc
