let the nos be x & y
\n" ); document.write( "so x+y=16
\n" ); document.write( "& x-y=4
\n" ); document.write( "by adding both eqns we get
\n" ); document.write( "2x=20
\n" ); document.write( "or x=10
\n" ); document.write( "fro eqn 1
\n" ); document.write( "y=16-10=6
\n" ); document.write( "so the nos are 10 & 6
\n" ); document.write( "
\n" );
