Where did you get this question from? If you solve the equations, you will get;
x = -4/5 and y = -12/5; so (-4/5, -12/5) will be the common coordinates for both the equations, where these two lines will intersect.
x = -4/5 and y = -12/5; so (-4/5, -12/5) will be the common coordinates for both the equations, where these two lines will intersect.

None of the choices are correct.
3x=-2x-4
5x=-4
x=-4/5
So the point where they will meet is (-4/5,-12/5).[/list]
