Answer/Step-by-step explanation:
The equation,
has one solution, x.
The value of x that will make the equation true, that is the number we can substitute for x into the equation that will make what we have on our left side equal to what we have on our right side is -4.
Substitute -4 for x in the equation and simplify:
.
Simplifying the equation:
(this is true).
A value of x that can make the equation false is 4.
Thus, replace x with 4, then simplify.


(false. 5 ≠-5)
