Subtract algebraic fractions where the denominators are linear expressions, eg (x + 5) and (x - 3), and the numerators are single terms STEP \( 2 \)

Which of the options is a correct second step to express the following as a single fraction?
\(
\begin{array}{c}
\frac{9}{x+3}-\frac{2}{x} \\
=\frac{9 x}{x(x+3)}-\frac{2(x+3)}{x(x+3)}
\end{array}
\) \( \frac{9 x-2(x+3)}{x(x+3)-x(x+3)} \)
