Help!! Math Problem that sounds easy but actually kind of hard? 11th grade level? maybe lower

53 cattle-53 cattle, 12 people.......

At a cattle pen at the county fair, Jody counted 65 heads and 236 legs. How many cattle and how many workers were there in the pen at that time?

Thanks so much in advance!

-

p+c=65 (head)
2p+4c=236 (legs)
p is for people c is for cattle

p=65-c
2(65-c)+4c=236
130-2c+4c=236
130+2c=236
2c=236-130
2c=106
c=106/2=53

53+p=65
p=65-53=12

12 people, 53 cattle
