Farmer Brown counted 20 pigs and chickens in the farm yard. He counted a total of 54 legs. How many of each were there? (How many pigs were there? How many chickens were there?)

We know: There are 20 pigs and chickens in TOTAL (not 20 of each)

Pigs have 4 legs

Chickens have 2 legs

The question asks me to show step-by-step how I got to the answer with explanation of each step in words.

Thank you:)
