    The son is five years old

    Step-by-step explanation:

    Let the son's age be x

    A man is five as old as his son, 5x

    In five years, he would be three times as old as his son

    In five years: son would be x+5

    Father 5x+5

    3 (x+5) = 5x+5

    3x+15=5x+5

    Collect like terms

    15-5=5x-3x

    10=2x

    Divide by 2

    10/2=2x/2

    x=5

    The son is five years old
