    A system of equations means that both equations need to be true in the same time.

    Since y is equal with 3x-7 and 2x+7 then those must be equal with eachother.

    3x-7=2x+7

    3x-2x=7+7

    X=14

    Now that we know x use any given equation of y and substitute x with 14

    Y=3•14-7=35

    Solution: x=14, y=35
