A bookstore sold 18,000 paperbacks one month. This was 10% less than the number of paperbacks the store sold the previous month. The following equation represents this situation, where x represents the number of paperbacks sold the previous month.

x − 0.1x = 18,000

How many paperbacks did the store sell in both months combined?
