2%2F8=%28n%2B4%29%2F%28n-4%29 Start with the given equation.


2%28n-4%29=8%28n%2B4%29 Cross multiply.


2n-8=8n%2B32 Distribute.


2n=8n%2B32%2B8 Add 8 to both sides.


2n-8n=32%2B8 Subtract 8n from both sides.


-6n=32%2B8 Combine like terms on the left side.


-6n=40 Combine like terms on the right side.


n=%2840%29%2F%28-6%29 Divide both sides by -6 to isolate n.


n=-20%2F3 Reduce.


----------------------------------------------------------------------

Answer:

So the answer is n=-20%2F3 which approximates to n=-6.667.
