there are 35 pigs and 65 chickens
35 pigs x 4 legs= 140
65 chickens x 2 legs= 130
140+ 130= 270 legs

These algebra teachers are always busy with math!
let c be the number of chickens
let p be the number of pigs
in terms of heads
c + p = 100 [I]
in terms of legs
2c + 4p = 270 [II]
now solve

Ok, clarify this a little more for me. Was the algebra teacher driving by a farm on Mars or on Earth?
