According to the 2000 Census the population of Canton was 7,720. Holly Spring's population was 3,200. Canton's population increases at a rate of 80 people a year and Holly Spring's population increases by 120 people a year. Which equation may be used to determine the number of years before the populations are equal?

• $200x=10920$

• $7720+12x=3200+80x$

• $7720x+80=3200x+120$

• $7720+80x=3200+120x$
