Question 379503
Let x=number of chicks
And let y=number of pigs

We are told that:
x+y=100----------------------------eq1
We are also told that:
2x+4y=270------------------------------eq2

Multiply eq1 by 2 and then subtract it from eq2 and we get:
2y=70
y=35----------------number of pigs
Substitute this into eq1
x+35=100
x=65---------------------------number of chicks
CK
35+65=100
100=100
and
4*35+2*65=270
140+130=270
270=270

Hope this helps---ptaylor
