Joe has a collection of 35 DVDs, he gets 8as gift. He bought the rest over three years. If he bought the same number of movies each year how many movies did he buy last year?

So the number he bought was 35-8. And since the total bought has been bought the same amount over the past three years. 3n=27. The n is the amount bought per year. n=9.
