\r\n" );
document.write( "We look at the first sentence:
Janet is three times as old as James.
\r\n" );
document.write( "Let James' age be x \r\n" );
document.write( "Then Janet's age is 3 times x or 3x.\r\n" );
document.write( "\r\n" );
document.write( "We look at the second sentence:
The sum of their ages is 64.
\r\n" );
document.write( "x + 3x = 64\r\n" );
document.write( "    4x = 64\r\n" );
document.write( "     x = 16\r\n" );
document.write( "\r\n" );
document.write( "Therefore James' age = 16\r\n" );
document.write( "And Janet's age = 3x = 3(16) = 48\r\n" );
document.write( "\r\n" );
document.write( "Now do yours exactly the same way.\r\n" );
