make an equation system that represents the problem
eg. h stands for the number of hamburgers, c stands for the number of cheeseburgers.
An equation for "a combined total of 282 hamburgers and cheeseburgers" is
⇒ h + c = 282 (first equation)
An equation for "The number of cheeseburgers sold was two times the number of hamburgers sold" is
⇒ c = 2h (second equation)
Second,
solve the equation system by subtitution method. Subtitute c with 2h from the second equation to the first equation
h + c = 228
h + 2h = 228
3h = 228
h = 228/3
h = 76
Answer
The number of hamburgers sold is 76
