Answer:
Third answer.
Explanation:
To simplify, we can factor 'x' from the equation, giving us:
![(x(1))/(x(4 + x)) = (1)/(x+4)](https://img.qammunity.org/2021/formulas/mathematics/college/9wpg00kjasnj88lfcnf3t9rpyr5s8y5zij.png)
However, we must put a domain restriction to ensure that the denominator will not equal 0. This means that 'x+ 4' cannot equal zero. Therefore, x ≠ -4.
The third answer is correct.
