five years later they had a son (Uncle Thomas).
Uncle Thomas lived exactly one half as long as Grandpa.
Then Grandpa died four years after Uncle Thomas passed.
How many years did my grandpa (James) live?
:
Let a = Grandpa's age
:
a = 1%2F6a + 1%2F12a + 1%2F7a + 5 + 1%2F2a + 4
Multiply by the LCM (7 * 12 = 84), results:
84a = 14a + 7a + 12a + 84(5) + 42a + 84(4)
84a = 75a + 420 + 336
84a - 75a = 756
9a = 756
a = 756/9
a = 84 yrs grandpa's age when he made his final journey
