What progress can you make trying to solve this on your own? Please do not post multiple copies of the same topic.

Hi ! You simply add the terms that contain the same variable together and the terms that have no variables together. For example if you have $\displaystyle A=3+5x4+2.1x$ then you add the terms $\displaystyle 5x$ and $\displaystyle 2.1x$ together because they contain the same variable $\displaystyle x$ and you add the terms $\displaystyle 3$ and $\displaystyle 4$ In other way : $\displaystyle A=\left(5x+2.1x\right)+\left(34\right)=(5+2.1)x+(1)=7.1x1$ Is it clear for you ? In your question the variable is $\displaystyle n$. So try to do the same !
