You can put this solution on YOUR website!
Not enough info to know when you will never be exactly 3 times older than your son. you didn't give us your exact birth dates and times.

\n" ); document.write( "2011-1957=54
\n" ); document.write( "2011-1996=15
\n" ); document.write( "(x+54)=3*(x+15)
\n" ); document.write( "x+54=3x+45
\n" ); document.write( "9=2x
\n" ); document.write( "4.5=x
\n" ); document.write( "add 4.5 to 2011\r
\n" ); document.write( "\n" ); document.write( "check
\n" ); document.write( "58.5=3*19.5
\n" ); document.write( "ok
