Let x be the age to find out.


X = childhood + adulthood + time to marriage + 5 yrs (sons birth) + son' age + 4 years

X.  =.  X/6.      + x/12.        + x/7.      + 5.   +x/2.      + 4.

0 = x/6 + x/12 +x/7 _ x/2 + 9         (transposing x from LHS)

0 = 14x + 7x + 12x _ 42x + 84* 9.      (multiply by 84    Common denominator)

9x = 84*9.    (transpose x terms to,left)

So the age is. 84
