The solution is n is equal to negative 2 verified as a solution to the equation 1 point 4 n plus 2 is equal to 2 n plus 3 point 2 What is the last line of the justification?

Substitute n = −2 into both sides of the equation. The left side is 1.4(−2) + 2 = −2.8 + 2 = −0.8, and the right side is 2(−2) + 3.2 = −4 + 3.2 = −0.8. So the last line is −0.8 = −0.8, choice C.
