-2n + 6

Step-by-step explanation:

Combine like terms (terms with the same amount of variables).

Note the laws of signs:

Two additions signs: If there are two addition signs directly next to each other (which will not be shown very much), it means to add.

One addition sign & One negative sign: If there is one of each signs directly next to each other (as shown here), you must default it to negative and subtract.

Two negative signs: If there are two negative signs directly next to each other, you must default it to positive and add.

First, change the expression to signify how you should combine the terms:

5n + 6 + (-7n) = 5n - 7n + 6

Combine like terms:

(5n - 7n) + 6

-2n + 6

-2n + 6 is your answer.
