Let +a+ = Joe's age now
Let +b+ = his father's age now
-------------------------------
(1) +b+=+4a+
(2) +b+%2B+6+=+3%2A%28+a+%2B+6+%29+
--------------------------
(2) +b+%2B+6+=+3a+%2B+18+
(2) +-3a+%2B+b+=+12+
Substitute (1) into (2)
(2) +-3a+%2B+4a+=+12+
(2) +a+=+12+
and
(1) +b+=+4a+
(1) +b+=+4%2A12+
(1) +b+=+48+
-------------------
Joe is 12
His father is 48
