Solve
%28%284-v%29%29%2F%28%289-v%29%29 = 5%2F%28%28v-9%29%29
make the two fraction have the same denominator, factor out -1, that changes the signs
%28%284-v%29%29%2F%28-1%28v-9%29%29 = 5%2F%28%28v-9%29%29
which is
-%28%284-v%29%29%2F%28%28v-9%29%29 = 5%2F%28%28v-9%29%29
If we multiply both sides by (v-9) we just have:
-(4-v) = 5
Removing the brackets changes the signs
-4 + v = 5
Add 4 to both sides
v = 5 + 4
v = 9, however, all is for naught, because that would make division by 0, no solution
