    Side one will be x, and side two will be y.

    x = 2y

    x + y + 8 = 26

    Subtract 8

    x + y = 18

    Remember that x = 2y

    The only value that would make this expression true, is 6.

    12 + 6 = 18

    Now we can plug these values in to x + y + 8 = 26

    12 + 6 + 8 = 26

    That's it.
