    Maybe it is for you, @JacobRobloxian but I'm sure you didn't know how to do a problem like this at some point.

    Well first solve for x, then plug it in either of the equations to get a corresponding y, it doesn't matter which one you pick.

    |dw:1439928926327:dw| I would substitute what y equals in for the other equation.

    When you get the (x,y) that will be the point where the lines intersect.

    Try and plug in one of your choices for the x and y values. He gave you the right equations to help you input those values from your choices.

    I'm not sure what you mean. I subtracted 2 on both sides. How do you think that would simplify?

    |dw:1439929759309:dw| 3/2 is multiplied by x, so we need to divide by 3/2 to get x by itself.

    Your x/y value which was not used. 3/2x = 3 3/2x into 3. Consider, 3/2 x 2 = 6/2 6 divided by 2 is 3. Which would give you your answer. 2/1 = 2 3/2 * 2/1 6/2 x = 2
