Let the number of cows = x
\n" ); document.write( "Let the number of chickens = y
\n" ); document.write( "Total number of heads = x+y
\n" ); document.write( "Every cow has 4 legs and every chicken has 2 legs
\n" ); document.write( "Total number of legs = 4x+2y
\n" ); document.write( "Given, the number of legs was 16 more than twice the number of heads.
\n" ); document.write( " 4x+2y = 2(x+y)+16
\n" ); document.write( " 4x+2y = 2x+2y+16
\n" ); document.write( " 2x = 16
\n" ); document.write( " x = 8
\n" ); document.write( "Therefore the number of cows = 8
\n" ); document.write( "
\n" );
