**sarah**, Wednesday, January 23, 2008 at 8:02pmLet C=number of chickens and P=number of pigs

1. C+P=18

2. P=18-C (isolate a variable)

3. 2C+4P=50 (Each chicken has two legs, each pig has four legs, and adds up to 50 legs).

4. 2C+4(18-C)=50) Substitute 18-C for P because step 2 shows P=18-C.

2C+72-4C=50

72-2C=50

-2C= -22

C=11
