You can put this solution on YOUR website! Joe is 20,089 days old. I am 5886 days old. When will Joe be exactly twice my age in days?
Let the number of days needed be "x".
Equation:
20,089+x = 2(5886+x)
-------
20,089 + x = 11772 + 2x
-----
x = 8317 days
----------
Joe will be 20,089+8317 = 28,406 days old

You can put this solution on YOUR website! let joe be double my age after x days
after x days
joes' age = (20089+x)
My age = (5886+x)
(20089+x) = 2(5886+x)
920089=11772+2x
920089-11772=2x
8317 =2x
x=8317/2
x=4158.5
After 4185 days Joe will be double my age.

Let amount of days for Joe to be exactly twice my age (in days), be D
Then: 20,089 + D = 2(5,886 + D)
20,089 + D = 11,772 + 2D
D – 2D = 11,772 – 20,089
- D = - 8,317
D, or amount of days that Joe will be twice my age (in days) =  , or
