Answer:
x = -2
Step-by-step explanation:
Since we cannot divide by 0, the value of x which results in a denominator that is 0 is a value excluded from the domain;
This value can be found by setting the denominator equal to 0;
In this case, the denominator is -5x - 10 so we construct the following equation and solve;
-5x - 10 = 0
5x = -10
x = -2
