There are 85 double rooms and triple rooms in the accommodation department of Santai Hotel. If the number of double rooms is reduced by 8 and the number of triple rooms is reduced by 1, the number of two rooms is equal. let two people be x, three people be y, and the binary linear equation, equation 1: x+y=85. Equation 2: x-4=y-1. If you substitute it into the solution, x=62 rooms and y=23 rooms, that is, there are 62 rooms for two people and 23 rooms for three people. I don't know if it is right. I hope the landlord can give me the best answer.
