\n" ); document.write( "Sum of 2nd group of numbers is bn
\r
\n" ); document.write( "\n" ); document.write( "Average of (m+n) numbers is therefore: (am+bn)/(m+n) = k
\r
\n" ); document.write( "\n" ); document.write( "Solving for m:
\r
\n" ); document.write( "\n" ); document.write( "m = (kn-bn) / (a-k) , \"+a+%3C%3E+k+\"\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
\n" );
