What's n?!
15-1/6n=1/6n-1
15- [1/6]n= [1/6]n-1 add [1/6 ] n , to both sides
16 = [2/6]n 2/6 = 1/3
16 = [1/3] n multiply both sides by 3
48 = n
n is just a variable they use. You would just solve the equation for n.
I was wondering what number n was though... I know how to solve equations but this one stumps me
14/6n=1/6n-1
Cross multiply
84n-14=6n
+14 to both sides
-6n from both sides
78n=14
n=14/78
That is simplified to n=7/39
15-(1/6n)=(1/6n)-1
n=48
{nl} Oh, I hadn't realized that it was 15 - [1/6]n. Sorry.
