\n" ); document.write( "\"x%2F2\" = number of games they win out of \"x\" more games
\n" ); document.write( "--------

\n" ); document.write( "\"+15+%2B+x%2F2+=+.6%2A%2820+%2B+x%29+\"
\n" ); document.write( "\"+15+%2B+.5x+=+12+%2B+.6x+\"
\n" ); document.write( "\"+.1x+=+3+\"
\n" ); document.write( "\"+x+=+30+\"
