    Answer: Peters age is 25 years old.

    The two equations that can be written given the information are:

    h = x/5 + 7 and 4h = 2x - 2

    When x = Peter's age and h = Phil's age.

    If we use substitution, we can come up with the equation:

    4 (x/5 + 7) = 2x - 2

    4x/5 + 28 = 2x - 2

    4x + 140 = 10x - 10

    150 = 6x

    25 = x

    Solving this for x, we give us that Peter's age is 25.
