Answer:

Step-by-step explanation:
We have been given that n=-2 verified as a solution to the equation
.
As n=-2 is the solution for our given equation, so it will satisfy our equation.
Let us substitute n=-2 is our given equation.



Since the value of n satisfies our equation, therefore, last line of the justification will be
.
