The rooms in the mountain hotel are double and triple. Double rooms are 25 and triple are 17 more. How many rooms are there in this hotel?

Result

s =  67

Solution:

a=25 b=a+17=25+17=42 l=2⋅ a+3⋅ b=2⋅ 25+3⋅ 42=176 s=a+b=25+42=67a=25 \ \\ b=a+17=25+17=42 \ \\ l=2 \cdot \ a+3 \cdot \ b=2 \cdot \ 25+3 \cdot \ 42=176 \ \\ s=a+b=25+42=67
