Let +a+ = Kofi's age now
Let +b+ = Ama's age now
------------------------------------
(1) +a+=+3b+
(2) +a+-+9+=+4%2A%28+b+-+9+%29+
---------------------------------
(2) +a+-+9+=+4b+-+36+
Plug (1) into (2)
(2) +3b+-+9+=+4b+-+36+
(2) +b+=+27+
and
(1) +a+=+3b+
(1) +a+=+81+
--------------------
Kofi is 81
Ama is 27

For your attention: 

      " . . .  Three years as old as . . . "  is not English form --- it is absurdist form.



      Same as  " . . . four years as old as . . . ".
