A farmer raises pigs and chickensthe has 220 animals with atotal of 700 legs how many does the have?

Here's how to solve this classic word problem:

Let:

* `p` represent the number of pigs

* `c` represent the number of chickens

Set up the equations:

* Equation 1 (Total animals): p + c = 220

* Equation 2 (Total legs): 4p + 2c = 700 (Pigs have 4 legs, chickens have 2)

Solve for the variables:

1. Solve for 'p' in Equation 1:

p = 220 - c

2. Substitute this value of 'p' into Equation 2:

4(220 - c) + 2c = 700

3. Simplify and solve for 'c':

880 - 4c + 2c = 700

-2c = -180

c = 90

4. Substitute the value of 'c' back into Equation 1 to find 'p':

p + 90 = 220

p = 130

Answer: The farmer has 130 pigs and 90 chickens.
