    Answer:

    Daniel (now) is 3 years old,  (2 years ago) is 1 year old.

    Kevin (now) is 6 years old,   (2 years ago) is 4 years old.

    Step-by-step explanation:

    Now:

    -Kevin: k = d + 3

    -Daniel: d

    2 years ago:

    -Kevin: k – 2 = 4(d – 2)

    -Daniel: d – 2

    We have the equation:

    (k – 2) + 2 = k

    4(d – 2) + 2 =  d + 3

    4d – 8 + 2 = d + 3

    3d – 6 = 3

    3d = 9

    d = 3

    k = d + 3 = 3 + 3 = 6
