On Wednesday, a local hamburger shop sold a combined total of 372 hamburgers and cheeseburgers. The number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were sold on Wednesday?

let x = number of hamburgers sold
2x = number of cheeseburgers sold
x + 2x = 372
3x = 372 

Divide both sides by 3
 
x = 124

124 hamburgers were sold
