document.write( "\r\n" );
document.write( "Let M be the money earned by Tom.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then Fred earned  money.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Total they earned is this sum  T =  = .    (1)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "We want to express M via T.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From (1),  M = .    (2)\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is the expression you want to get.\r\n" );
