Question

| 7.5 - 5 n | = 2.5

Answer 1

|7.5 - 5n| = 2.5
7.5 - 5 = 2.5
|2.5n| = 2.5
n = 1,-1


|2.5(-1)| = 2.5
|-2.5| = 2.5
2.5 = 2.5

|2.5(1)|
|2.5| = 2.5
2.5 = 2.5

Answer 2

Nice work @TrashMan914, but next time try and help them find the answer rather than just give it to them.

Answer 3

I'm usually the one that says that, honestly. But, I really couldn't find a way to explain how to solve it, other than simply giving him the steps. I could have explained what Absolute Value was, but I merely assumed that he had no clue where to start on the problem.
