a local hamburger shop sold a combined total of 321 hamburgers and cheeseburgers.
hamburgers+%2Bcheeseburgers=321.......eq.1
The number of cheeseburgers sold was+two+times the number of hamburgers sold.
cheeseburgers=2%2Ahamburgers.........eq.2
hamburgers+%2B2%2Ahamburgers=321.......eq.1
3%2Ahamburgers=321
hamburgers=321%2F3
hamburgers=107

=>107+hamburgers were sold on Thursday
