Answer
Doesn't make sense.
Work Step by Step
To simplify,.
1. Factor the numerator and the denominator completely.
2. Divide both the numerator and the denominator by any common factors.
7 is a factor of both the numerator and the denominator in $\displaystyle \frac{7}{14x}$,
so dividing both by 7 can be done,
but, it is not a factor of the denominator of $\displaystyle \frac{7}{14+x}, $so
for the second expression, this can not be done.
