Diophantus of Alexandria, a third century mathmatician, lived one-sixth of his life in childhood, one-twelfth in his youth, and one-seventh as a bachelor. Then he married and five years later had a son. The son died four years before diophantis at half the age diophantus was when he himself died. How long did he live? : Let his age at death = x: : childhood + youth + young man + 5 yrs + son's age + 4 yrs = His age at death 1/6x + 1/12x + 1/7x + 5 + 1/2x + 4 = x : A good common denominator is 84, mult equation by 84 and you get: 14x + 7x + 12x + 420 + 42x + 336 = 84x 75x + 756 = 84x 75x - 84x = - 756 - 9x = - 756 x = -756/-9 x = 84 years old
