13-n=9. i think.
The question is ambiguous so the answer is one of:3/n - 5 or 3/(n-5)
"n divided into 3" = 3/n
18-(3*d) or 18-3d
3n is the simplest, but you could also write it as 3*n or 3.n or 3xn. The problem with the last form is that it could represent the product of 3 and x and n.
3 - x
3n-7
13-n=9. i think.
n/3 - 2 = 6 n/3 = 8 n = 24
(3 + -8) - 8
18-d3
If ten times the number n decreased by 13 is equal to the square of the same number n increased by 3, then the value of n is either 8 or 2.

18 - 3n
It depends on how the statement is read. If there's a pause after 'three', it's... (n - 3)(n + 8) Otherwise, it's... n - 3(n + 8)
