Cancel out 11 from numerator and denominator then it will yield: 1/(1+x)

It's a relatively simple one. 11/(11+11x) = 11/11(1+x)= 1/(1+x). The only bizarre solution will be if 1+x is 0. But that will not be the case as the test question said X is not -1.
So Answer is C

We can simplify the given expression by first factoring 11 from each term of the denominator and then cancelling:

11/[11(1 + x)] = 1/(1 + x)

Answer: C
