Subtract 9 from each side of the equation to get rid of 9 on the right, so that 8h is alone on the right side of the equation.

Let's start with the equation you provided:

\[
h - 3 = 9h + 9
\]

Now, we want to subtract 9 from both sides of the equation:

\[
h - 3 - 9 = 9h + 9 - 9
\]

This simplifies to:

\[
h - 12 = 9h
\]

Next, we want to isolate \(h\) on the left side. To do that, we can subtract \(h\) from both sides:

\[
h - h - 12 = 9h - h
\]

This simplifies to:

\[
-12 = 8h
\]

Now, if you want to express this in terms of \(h\), you can divide both sides by 8:

\[
h = -\frac{12}{8}
\]

This further simplifies to:

\[
h = -\frac{3}{2} \quad \text{or} \quad h = -1.5
\]

So the final answer is \(h = -\frac{3}{2}\).
