Answer: 5n+10
Step-by-step explanation:
Add like terms, so like terms would be the numbers who have the same variables and same amount of variables. 8n and -3n are like terms, but 8n and -3n^2 would not because the amount of variables are different. You would just add all of them together basically. 6+4 is 10 and 8-3 is 5, so you get 5n+10.
