The value as in adding them is 19

We can begin by rearranging this into multiplication:

Now we can factor the numerators and denominators:

The factors
(x+4) and
(x+2) cancel out, leaving us with:

Our answer comes out to be:

or

Based on the numerator of the second fraction (since we used its inverse), the denominators of both, and the factors we canceled out earlier, the restrictions are
x ≠ -4, -3, -2, -1, 4
