<em>Additional comment</em>
Even if you extend the domain to complex numbers, there are no solutions. The f(x) = |x| function always returns a positive real value, even for complex numbers.
Answer:

Step-by-step explanation:
So we have the equation:

First, let's subtract 9 from both sides:

Divide both sides by -4:

Add 1 to both sides:

Divide both sides by 2:

And we're done!
