\r\n" );
document.write( "\r\n" );
document.write( "Let the desired year be x years before 2000 or the year 2000-x.\r\n" );

document.write( "x years before 2000 Donald was 12-x and his father was 40-x.\r\n" );
document.write( "\r\n" );
document.write( "So we want 12-x to be th of 40-x.  To say that in algebra,\r\n" );
document.write( "\r\n" );
document.write( "          12 - x = (40 - x)\r\n" );
document.write( "\r\n" );
document.write( "Clear of fractions by multiplying both siades by 8\r\n" );
