Answer:
Explanation:
If you ignore the 7x for the moment, you can see that the numerator can be factored into (x-5)(x+1), and the denominator can factored into (x-5)(x+3).
The (x+5)s can cancel out, so you are left with
times
. Since 7x/7x is just equal to 1, our final answer is (x+1)/(x+3).
Hope this helped! :)
