Answer:
- one-story: 10 doors
- two-story: 13 doors
Step-by-step explanation:
Let o and t represent the numbers of doors in a one-story and a two-story house, respectively.
2o +t = 33 . . . . . . . . west-side doors
8o +t = 93 . . . . . . . . east-side doors
__
6o = 60 . . . . . subtract the first equation from the second
o = 10
2(10) +t = 33 . . . . substitute for o in the first equation
t = 13 . . . . . . . . subtract 20
__
Each one-story house has 10 doors, and each two-story house has 13 doors.
