n + 5n
I am unsure what you are asking for, however I will assume you are asking`n+5n=?`
To solve this you must search for all like terms, in this case the two monomials n and 5n. The blank space in front of the solitary n is actually a 1, as we still consider there to be one n in the problem. If we insert this 1 we get: `1n+5n=?`
When adding monomials, add their constants together, in this case 1 and 5. Adding these together you get 6n as your answer.
The reason the n does not become squared or anything else strange is, due to it being a variable, we actually aren't sure what the value is. We can only manipulate the constants the variable is multiplied by. Hope that helps!
If n=1/6 then you are assuming the original equation given was `n+5n=1`
Since that was not given I would be careful about including that as an answer.
