Answer: n = 1/5
Step-by-step explanation: You use the Distribution Property to get 5n - 5/10 which is just 1/2. Then, it's 5n - 1/2 = 1/2, so next you add 1/2 to both sides to get 5n only by itself. So now the problem look like this: 5n = 1. Then, to get the answer to n, divide 5 to both sides and n = 1/5.
