If there are t tourists and r rooms,

t = 6r-9
t = 3(r+4)

6r-9 = 3r+12
3r = 21
r = 7
so, t=33
I want clear explanation plz
Explanation you have to give step by step and clearly
Chutiya hai kya
T=6r-9
T=3(r+4)
6r-9=3(r+4)
6r-9=3r+12
6r-3r=12+9
3r=21
r=7
Now 3(r+4) is equal to
3(7+4)
3×11
33
Thus,the answer is 33
