Answer: H is the group 10H and -5H is in.
Step-by-step explanation:
When you are doing this equation you classify group by their variables. If they do not have a vairable they are called "constants". It is a simplified version of 5h + 9, this is because of the way you do the problem. You are going to add 3 + 6. Then you are going to add 10H + ( - 5H ). So you are going to end up with 5H and 9 from your equations. Now you are going to form the equation 5H + 9.
