Beds

At the summer camp, there are 41 chalets. Some rooms are 3-beds, some 4-beds. How many campers from 140 are living in 3-bed?

Result

x =  72

Solution:

 41=a+b 3a+4b=140  a+b=41 3a+4b=140  a=24 b=17  x=3 a=3 24=72 \ \\ 41 = a+b \ \\ 3a+4b = 140 \ \\ \ \\ a+b = 41 \ \\ 3a+4b = 140 \ \\ \ \\ a = 24 \ \\ b = 17 \ \\ \ \\ x = 3 \cdot \ a = 3 \cdot \ 24 = 72
