Answer
$\frac{5x^2y-6}{x^2}$
Work Step by Step
Given \begin{equation}
5 y-\frac{6}{x^2}.
\end{equation} First rewrite $5y$ as a fraction: \begin{equation}
5y= 5y\cdot\frac{x^2}{x^2}= \frac{5x^2y}{x^2}.
\end{equation} Find the LCD of the fractions which is: $\mathbf{LCD}=x^2$. Perform subtraction:
\begin{equation}
\begin{aligned}
5 y-\frac{6}{x^2}&=\frac{5x^2y}{x^2}-\frac{6}{x^2} \\
&= \frac{5x^2y-6}{x^2}.
\end{aligned}
\end{equation}
