You can put this solution on YOUR website!
Let +m+ = Maya's age now
Let +f+ = father's age now
--------------------------
(1) +f+=+4%2A%28+m+-+3+%29+
(2) +f+=+36+
-------------------
(1) +36+=+4%2A%28+m+-+3+%29+
(1) +36+=4m+-+12+
(1) +4m+=+48+
(1) +m+=+12+
Maya is 12 now
--------------
check:
(1) +f+=+4%2A%28+m+-+3+%29+
(1) +36+=+4%2A%28+12+-+3+%29+
(1) +36+=+4%2A9++
(1) +36+=+36+
OK
