Answer:

n-6h+9

first you subtract the ns from each other because those are the only like terms

goldenpoo21
3n-2n-6h+9

So first you get all the like terms together from calculating the addition sequence here from their coefficients

So

(3-2-6)x+9

Now you calculate the difference in the parenthesis

-5x+9 is your answer and you leave it like that because you can’t really do anything else just leave it how it is
