Answer:

350

Step-by-step explanation:

If x is the number of hamburgers and y is the number of cheeseburgers, then:

x + y = 764

y = x + 64

Solve the system of equations with substitution or elimination. Using substitution:

x + x + 64 = 764

2x + 64 = 764

2x = 700

x = 350

350 hamburgers were sold.
