Erica receives 35 packages. Speedy delivery delivered twice as many as Ralphs Express, while Ralphs express deliverd five more then sendquick package service. How many did each service deliver erica?
=====
sd = 2re
re = sp+5
sd + re + sp = 35
------------------------
Substitute for sd and sp and solve for re:
2re + re + re-5 = 35
4re = 40
re = 10 (# of packages delivered by Ralph's Express)
-----
sd = 2re = 20 (# of packages delivered by Speedy Delivery)
------
sp = re-5 = 5 (# of packages delivered by Sendquick Package)
