[tex]\text{First you have flip the equation around}\\\\\text{Like: -0.8n = 4}\\\\\text{Once when you have that portion out the way, DIVIDE by -0.8 on the sides}\\\\\text{Like: }\bf{\dfrac{-0.8n}{-0.8}=\dfrac{4}{-0.8}}\\\\\text{Cancel out:}\bf{\dfrac{-0.8n}{-0.8}}\text{ because it equals to 1}\\\\\text{Keep:}\dfrac{4}{-0.8}\text{ because it solves for the answer}\\\\\\\\\boxed{\boxed{\text{Answer: n = -5 }}}\checkmark[/tex]
[tex]\text{Good luck on your assignment and enjoy your day!}[/tex]
