A farmer owns a total of 19 ducks and horses. The ducks and horses have 64 legs altogether. How many horses are there?

\(x \ ducks\)

\(19-x \ horses\)

\(2x+4(19-x)=64\) calculate

\(2x+76-4x=64\) sort them

\(4x-2x=76-64\) calculate

\(2x=12\) divide by 2

\(x=6\ ducks\)

\(19-x =19-6 =13 \ horses\)

\(2\times 6+4\times13=64\)
