Formula

Well start by adding all the numbers together, then divide by how many numbers, which is 15
Step-by-step explanation:
-16 + 3n = - 8 - 5n
Bringing like terms on one side
3n + 5n = - 8 + 16
8n = 8
n = 8/8
N = 1
1. You can subtract everything with the same “value” so that means you can subtract 3x from 6x, 5y - 5y and 39 - 27. This will give you: 3x + 0 = 12. Because 0 isn’t anything you get 3x = 12. Dividing everything by 3 you get x = 4
