Answer:
X = 5
Step-by-step explanation:
I think there a problem with the question, If there is one less person in the group then the payment by each remaining person is must more than $2 than the previous, because the rent cost unchanged but the number of people in the group decreased.
Before, cost per person : 
After cost per person: = 
However, the payment by each remaining person is more than $2 than the previous, so
= + 2
<=> 
- 2x -40 = 0
<=> X = 5
You first subtract 5x from both sides and end up with -3y=21-5x. In order to isolate the variable you need to divide -3 from both sides. Your equation would then be y= -7+ 5/3x. I hope this helps love! :)
