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?\n0.8 = 0.8\n-0.8 = -0.8\n3 = 3\n-3 = -3

Answer

Explanation:

Step1: Substitute n = - 2 into left - hand side

$1.4\times(-2)+2=-2.8 + 2=-0.8$

Step2: Substitute n = - 2 into right - hand side

$2\times(-2)+3.2=-4 + 3.2=-0.8$

Answer:

B. $-0.8=-0.8$
