Question 1075208
On Saturday, a local hamburger shop sold a combined total of 
243 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Saturday?
------
Equations:
h + c = 243
c = 2h
--------------
Substitute for "c" and solve for "h"::
h + 2h = 243
3h = 243
h = 81 (# of hamburgers sold on Saturday)
