    Let x be the current age of Mr. Chan's son, so (x + 32) is the current age of Mr. Chan.

    (x + 6) + [(x + 32) + 6] = 50

    2x + 44 = 50

    x = (50 - 44) / 2 = 3

    Mr. Chan's son is 3 years old.

    Assume Mr chan's age is x and his son's age is s

    6 years later:

    (x - 32 = s) = (x + s = 50)

    (x = 32 + s) = (x = 50 - s)

    32+s = 50-s

    32+2s= 50

    2s=18

    s=9

    9-6=3

    His son is 3

    Let x+32 and x be the present ages of Mr Chan and his son

    then x+38 and x+6 will be the ages after 6 years

    (x+38)+(x+6)= 50

    2x + 44 = 50

    x=3
