He solution is n = –2 verified as a solution to the equation 1.4n + 2 = 2n + 3.2. what is the last line of the justification?

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 .
