-x+-+5%2F%283-x%29
Rewrite as an addition:
-x+%2B+%28-5%29%2F%283-x%29
If you multiply the top and bottom of the fraction by -1:
-x+%2B+%28%28-5%29%2F%283-x%29%29%2A%28%28-1%29%2F%28-1%29%29
Simplifying we get:
-x+%2B+5%2F%28-3+%2B+x%29
Using the Commutative property in the denominator:
-x+%2B+5%2F%28x+%2B+%28-3%29%29
Rewriting the denominator as a subtraction:
-x+%2B+5%2F%28x+-+3%29
So the answer is (2).
