Answer:

D. n=3

Step-by-step Step-by-step explanation:

8-2n-6n= –16

Take 8 to the other side

-2n-6n= -16-8

Solve them

-8n = -24

Take -8 to the other side


n \: = ( - 24)/( - 8)

n = 3

\huge\text{Hey there!}


\huge\textbf{Equation:}


\mathbf{8 - 2n - 6n = -16}


\huge\textbf{Solving for the answer:}


\mathbf{8 - 2n - 6n = -16}


\huge\textbf{Combine the like terms:}


\mathbf{(-2n - 6n) + 8 = -16}


\mathbf{-2n - 6n + 8 = -16}


\mathbf{-8n + 8 = -16}


\huge\textbf{Subtract \boxed{\bf 8} to both sides:}


\mathbf{-8n + 8 - 8 = -16 - 8}


\huge\textbf{Simplify it:}


\mathbf{-8n = -16 - 8}


\mathbf{-8n = -24}


\huge\textbf{Divide \boxed{\bf -8} to both sides:}


\mathbf{(-8n)/(-8) = (-24)/(-8)}


\huge\textbf{Simplify it:}


\mathbf{n = (-24)/(-8)}


\mathbf{n = -24 / -8}


\mathbf{n = 3}


\huge\textbf{Therefore, your answer should be:}


\huge\boxed{\textsf{Option D. \boxed{\frak{n = 3}}}}\huge\checkmark


\huge\text{Good luck on your assignment \& enjoy your day!}
