\n" ); document.write( " They then played N remaining games and won all of them.
\n" ); document.write( " If they won exactly half of all the games they played,
\n" ); document.write( " what is the value of N?
\n" ); document.write( ":
\n" ); document.write( "2(4 + n) = (15 + n)
\n" ); document.write( "8 + 2n = 15 + n
\n" ); document.write( "2n - n = 15 - 8
\n" ); document.write( "n = 7 games
\n" ); document.write( ":
\n" ); document.write( "Check
\n" ); document.write( "they won: 4 + 7 = 11 games
\n" ); document.write( "total games: 15 + 7 = 22 games
