Assuming the problem is:
f%2F%28-3%29 + 5 = 8
:
f%2F%28-3%29 = 8 - 5
:
f%2F%28-3%29 = 3
:
Multiply both sides by -3
f = 3 * -3
f = -9
:
You can check this: replace f with -9
%28-9%29%2F%28-3%29 + 6 = 8
+3 + 5 = 8

--------------------
f/-3 + 5= 8
(f/-3) + 5 = 8
f/-3 = 3
f = -9
===============
f/(-3 + 5) = 8
f/2 = 8
f = 16
============
f/-(3+5) = 8
f/-8 = 8
f = -64
You need to add parentheses to eliminate the ambiguity.
