Answer

$x<2$

Work Step by Step

Create a table of values of $x$ and $y$ where $x$ is positive and $y$ is formulated by $y=\frac{5}{x-2}$. $\begin{matrix} \hline x&y\\ \hline 0&-2.5\\ 0.5&-3.333\\ 1&-5.0\\ 1.5&-10.0\\ 2&\text{Error}\\ 2.5&10.0\\ 3&5.0\\ \hline \end{matrix}$ In the table, we get two conditions: $y<0$ for $x<2$ and $y>0$ for $x>2$. Equivalently, $\frac{5}{x-2}<0$ if $x<2$ and $\frac{5}{x-2}>0$ if $x>2$. Thus, the solution to the inequality is $x<2$.
