A farmhouse shelters 10 animals some are pigs and some are ducks altogether there are 36 legs how many of each animal are there?

Sagot :

2x+4y=36 legs
2 for the two legged animals and 4 for the four legged animals
There are 10 animals so insert numbers that add up to 10 in for x and y
In this case x=2 y=8
Hope this helps!
