An employee at a construction company is ordering interior doors for some new houses that are being built. There are 4 one-story houses and 2 two-story houses on the west side of the street, which require a total of 62 doors. On the east side, there are 5 one-story houses and 3 two-story houses, which require a total of 85 doors. Assuming that the floor plans for the one-story houses are identical and so are the two-story houses, how many doors does each type of house have?
