You can put this solution on YOUR website!
Let +a+ = my age now
Let +b+ = my brother's age now
-----------------------------------
(1) +a+=+2b+
(2) +a+%2B+2+=+4%2A%28+b+-+5+%29+
----------------------------
(2) +a+%2B+2+=+4b+-+20+
(2) +a+=+4b+-+22+
Plug (1) into (2)
(2) +2b+=+4b+-+22+
(2) +2b+=+22+
(2) +b+=+11+
and
(1) +a+=+2b+
(1) +a+=+2%2A11+
(1) +a+=+22+
----------------------
I am 22 today
----------------
check:
(2) +a+%2B+2+=+4%2A%28+b+-+5+%29+
(2) +22+%2B+2+=+4%2A%28+11+-+5+%29+
(2) +24+=+4%2A6+
(2) +24+=+24+
OK
