Santa is working with his helpers. He counts 89 heads and 230 feet. How many reindeer and elves are there not including him.

reindeer have 4 feet
elves have 2
this would make sense if I was finding one not both!
Please help me

r + e = 89 ... they each have one head

4 r + 2 e = 230 ... 4 feet for reindeer and 2 feet for elves

multiply 1st eqn by 2 , and subtract from 2nd eqn ... this eliminates e

solve for r , then substitute back to find e
wait
4(2)=8
8+2e=230
