I think I add 1 to both sides, so now I have..
And then, to get n by itself I divide 7 into both sides, so now I have..
n=1 is what I get, but I'm not sure, could someone please check this for me?

No. Hang your head in shame :)
Multiply both sides by 8
add one to each side, then divide each side by 7

first you multiply each side by 8 to get
7n - 1= 48
now add 1 to each side
7n = 49
divide both sides by 7
n = 7
check: in original
((7(7) -1 1)/6
