Answer:
x = -5
Step-by-step explanation:
-9(x+3) = -9x-27
Add 27 onto both sides and get -9x = 45
Divide -9 on both sides and you'll see that x = -5 because 45/-9
Let's call the number of members x. We have x + 10 people who each pay $5, resulting in a sum of $600.
5(x+10) = 600
5x + 50 = 600
5x = 550
x = 110
