Answer:
subtract 5 from each side z=2
Step-by-step explanation:
First step: Factor the expression.
(x + 8) / (x - 6)(x + 4)
Set each factor of the denominator equal to zero.
x - 6 = 0 x + 4 = 0
add 6 to both sides subtract 4 from both sides
x = 6 x = -4
The function would be undefined if x = 6 or x = -4
Divide by x then is becomes p/x = 4-k
subtracte 4 which makes it -k=p/x -4
then divide by the negative which makes
k= -p/x +4
