Let h=number of hens and r=number of rabbits.
\n" ); document.write( "2h-4r=12
\n" ); document.write( "h-r=28
\n" ); document.write( ".
\n" ); document.write( "h=r+28
\n" ); document.write( "2(r+28)-4r=12
\n" ); document.write( "2r+56-4r=12
\n" ); document.write( "-2r=-44
\n" ); document.write( "r=22
\n" ); document.write( "h=50
