    Given your ordered pair you would assume a = 5, b = 2

    Set up both equations

    5 + 2 = 7

    7 = 7 (the numbers are equal so this correct)

    2 (5) - 8 = 2

    10 - 8 = 2

    2 = 2 (the numbers are equal so this is also correct)

    Because both equations work with the ordered pair they are the solution of the given system.
