Count Von Roo invited 141 monsters to his castle for a Halloween costume party, and all of the guests were either Yurbles (2 feeted monsters) or Rukis (4 feeted monsters). Because he had recently polished the floors, he provided socks for each of the guests so that they wouldn't scuff the floors.(adsbygoogle = window.adsbygoogle || []).push({});

If he required 350 socks total for his guests, how many of his guests were Yurbles?

Ok so at first i went and set it up as let y= yurbles and x=rikis so then i had two equations. 141=y+x and 350=y+x. so

y=141-x

350=(141-x)+x

But by doing that i have elimenated a variable i was trying to find. If anyone would know how i was to solve this problem it would be much appreciated.
