Answer:

n = 6

Step-by-step explanation:

[tex]16-2n=-8+4(n-3)\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\16-2n=-8+(4)(n)+(4)(-3)\\\\16-2n=-8+4n-12\qquad\text{subtract}\ 4n\ \text{from both sides}\\\\16-2n-4n=4n-4n-8-12\\\\16-6n=-20\qquad\text{subtract 16 from both sides}\\\\16-16-6n=-20-16\\\\-6n=-36\qquad\text{divide both sides by (-6)}\\\\\dfrac{-6n}{-6}=\dfrac{-36}{-6}\\\\n=6[/tex]
