The 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?

Solve:

1.4n + 2 = 2n + 3.2

Group like terms and change its corresponding signs.

1.4n - 2n = 3.2 - 2

Simplify each term:

-0.6n = 1.2

Find n by dividing each side with - 0.6

-0.6n/-0.6 = 1.2 / - 0.6

n = - 2

The last line of the justification is the division - 0.6n and 1.2 by - 0.6.
