Remember:
\n" ); document.write( "Fred's score= $\"F\"$
\n" ); document.write( "Nancy's score= $\"N\"$
\n" ); document.write( "Tiger's score= $\"T\"$
\n" ); document.write( " $\"F%2BN%2BT=223\"$ -----------------------------> eqn 1
\n" ); document.write( "But,
\n" ); document.write( " $\"F=N%2B3\"$ ,------> eq 2, Fred's score is 3 more than Nancy
\n" ); document.write( "and $\"T=F%2B7\"$ ----> eqn3, Tiger scored 7 more than Fred
\n" ); document.write( "IN eqn 2, we get $\"N=F-3\"$ -------> eq 4
\n" ); document.write( "We put eqn 3 and eqn 4 in eqn 1:
\n" ); document.write( " $\"F%2BF-3%2BF%2B7=223\"$
\n" ); document.write( " $\"3F=223%2B3-7\"$
\n" ); document.write( " $\"3F=219\"$ ---------> $\"cross%283%29F%2Fcross%283%29=cross%28219%2973%2Fcross%283%29\"$
\n" ); document.write( " $\"F=73\"$
\n" ); document.write( "via eqn 4: $\"N=73-3=70\"$
\n" ); document.write( "via eqn 3: $\"T=73%2B7=80\"$
\n" ); document.write( "In doubt? go back eqn 1:
\n" ); document.write( " $\"73%2B70%2B80=223\"$
\n" ); document.write( " $\"223=223\"$
