Question 208171
At work one day, Erica Franz received 45 packages. 
s + r + q = 45
Speedy Delivery delivered three times as many as ralph's Express, while Ralph's express delivered five more than Send Quick Package Service. 
s = 3r
r = s + 5
----------------------
How many packages did each service deliver to Erica?
s + r + q = 45
s - 3r + 0 = 0
s - r + 0 = -5
------------------------
I solved this system and got
unrealistic values for s,r and q.
