\r\n" );
document.write( "Let M = my age now\r\n" );
document.write( "Let Y = your age now,\r\n" );
document.write( "\r\n" );
document.write( "so my variables are consistent with those of Edwin McCravy.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "When it was happened when \"I was as old as you are now\" ? \r\n" );
document.write( "Obviously, it was (M-Y) years ago.\r\n" );
document.write( "\r\n" );
document.write( "So, your first equation is\r\n" );
document.write( "\r\n" );
document.write( "M = 3*(Y-(M-Y)).                     (1)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Now, when \"you will be my age\" ? - Obviously, in (M-Y) years.\r\n" );
document.write( "Therefore, your second equation is \r\n" );
document.write( "\r\n" );
document.write( "(M + (M-Y)) + (Y + (M-Y)) = 13370.   (2)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The rest is just a technique.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Answer. M = 5730, Y = 3820.\r\n" );
