Hi there!
The solution to the equation is n = 2.
Why?
All you need to do is subtract 1/5n from both sides:
3/5n+-4/5-1/5n=1/5n-1/5n
2/5n+-4/5=0
Then you need to add 4/5 to both sides...
2/5n+-4/5+4/5=0+4/5
2/5n=4/5
Finally you need to multiply both sides by 5/2
(5/2)(2/5n)=(5/2)(4/5)
n = 2
Hope this helps!
