Yes and you can work out x and y.

and 4y - x = 80
gives 12y -5y = 240,
y = 240/7 and x = 400/7

I'd say 6y-2x = 80

Actually since:
"which left Sabrina broke and gave Samantha a total of $80.00."

Samantha at this stage had all the money i.e. x + y and that's $80

Easy to solve both equations now!

why?
Sab gave sam y in a first illegal exchange and then 3y-x in the second and last one!
