What progress can you make trying to solve this on your own?

Please do not post multiple copies of the same topic.
Thanks from Ould Youbba

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 $\displaystyle A=3+5x-4+2.1x$ 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 :
$\displaystyle A=\left(5x+2.1x\right)+\left(3-4\right)=(5+2.1)x+(-1)=7.1x-1$

Is it clear for you ?

In your question the variable is $\displaystyle n$. So try to do the same !
Thanks from greg1313
