Answer:
Step-by-step explanation:
Given
w + 1 = d...........equation 1
d = 3w ...............equation 2
Now putting d = 3w in equation 1
w + 1 = 3w
3w - w = 1
2w = 1
w = 1 / 2
putting w = 1 / 2 in equation 2
d = 1 / 2 * 3
= 3/2
Hope it helps :)

Step-by-step explanation:
When 36 people are seated the room is 2/3 full.
