lets call w # of wins
\n" ); document.write( "and ......l # of losses
\n" ); document.write( ":
\n" ); document.write( "l=w+4--->l-w=4......eq 1
\n" ); document.write( ":
\n" ); document.write( "lets call Total matches (T)...we are given w=60%T and l=40%T
\n" ); document.write( ":
\n" ); document.write( "plug those values into eq 1
\n" ); document.write( ":
\n" ); document.write( ".6T-.4T=4
\n" ); document.write( ":
\n" ); document.write( ".2T=4
\n" ); document.write( ":
\n" ); document.write( "\"highlight%28T=20%29\"total matches
