given:\r
\n" ); document.write( "\n" ); document.write( "Halley's Comet appears about every 75 years.
\n" ); document.write( "One appearance was the year Mark Twain was born.
\n" ); document.write( "Let this year be \"x\"\r
\n" ); document.write( "\n" ); document.write( "The next appearance was the year he died.
\n" ); document.write( "Since Halley's Comet appears about every 75 years, means that Mark Twain lived 75 years too and died in year \"y+=+x%2B75\"\r
\n" ); document.write( "\n" ); document.write( "The sum of these two years is 3745. \r
\n" ); document.write( "\n" ); document.write( "\"x%2B%28x%2B75%29+=+3745\"\r
\n" ); document.write( "\n" ); document.write( "\"2x+%2B+75+=+3745\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+%283745-+75%29%2F2\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+1835\" the year Mark twain was born\r
\n" ); document.write( "\n" ); document.write( "\"y+=+x%2B+75\"\r
\n" ); document.write( "\n" ); document.write( "\"y+=+1910\" In year \"1910\" Mark Twain died.\r
