    You can use elimination to solve, which is where you multiply one or more equations to eliminate either the x's or y's.
    Multiplying the top equation by negative 2 will cancel the x's.
    Add the equations together.
    Divide by negative 3.
    Plug y=500 into any of the equations to figure out what x equals. Post if you want it checked.
