    oh, find y. i.e.x-y=-4 =>-y=-4-x =>y=4+x substitute this in your other eqn. and solve for x

    alternatively, make y the subject of both given equations and make them equal to each other.

    Solve both equations simultaneously with some points. You will get your intersection point then.

    2x+3y=-3 x-y=-4 2x-2y=-8 5y=5 y=1 x+1=-4 x=-3 x=-3 y=1

    start by doubling x-y=-4 and subtract equations

    intersection points are y=1 and x=-3 the the graph looks like this |dw:1338929983883:dw|
