You can put this solution on YOUR website!
Let +x+ = the older brother's age
+x+-+11+ = the younger brother's age
----------------
+%281%2F5%29%2A%28+x+%2B+x+-+11+%29+=+9+
+%281%2F5%29%2A%28+2x+-+11+%29+=+9+
+2x+-+11+=+45+
+2x+=+56+
+x+=+28+
and
+x+-+11+=+28+-+11+
+x+-+11+=+17+
--------------------
Their ages are 17 and 28
( there's no way to tell which brother is older
