Answer: 9.1 - 5.8n
Explanation:
All you need to do here is combine like terms.
Lets identify the two sets of like terms:
-3.8n and -2n
AND
3.1 and 6
So, you will add or subtract them as needed.
I will start by combining 3.8n and -2n
= 3.1 -3.8 -2n + 6
= 3.1 + 6 -5.8n
Now combine the 3.1 and 6.
= 9.1 - 5.8n
This is your answer!
