You can combine the same numbers with the same variables using the operation sign for each. For example, using your equation, you would combine the 3n and 4n which is 7n. So your equation would be
7n - 2

Combining like terms means that if u have two terms that are the same coefficient like 3n and 4n you have to either add or subtract because You have to have only one n in one side so u add 3 to 4 and u get 7n. Another example: 3n-2= 4n you would have to the same thing which is to add both. I'm sorry I'm not the best at explaining

a bathtub that hols 32 gallons of water contains 12 gallons of water you begin filling it and after 5 minutes the tub is full
kramer
Okay. I am guessing that you are asking for the amount of water poured per minute. The bathtub already holds 12 gallons and 32 - 12 is 20. The tub is full in 5 minutes. Let’s divide. 20/5 is 4. There are 4 gallons of water filled in the tub per minute.
