Start with the given equation

Subtract 9 from both sides.

Since the expression is never true (note: remember, the absolute value of any number is always positive), there are no solutions to

Also, notice if we graph and (just set each side equal to y and graph), we get:

Graph of (red) and (green)

and we can see that the two graphs never intersect. So there are no solutions.
