Answer

$x=\dfrac{1}{6}$

Work Step by Step

Using the properties of equality, the given equation, $ \dfrac{3}{2x}-\dfrac{2}{3x}=5 ,$ is equivalent to \begin{align*}\require{cancel} 6x\left( \dfrac{3}{2x}-\dfrac{2}{3x} \right)&=(5)6x &\text{(multiply by the $LCD$)} \\\\ 3(3)-2(2)&=30x \\ 9-4&=30x \\ 5&=30x \\\\ \dfrac{5}{30}&=\dfrac{30x}{30} \\\\ \dfrac{1}{6}&=x .\end{align*} Hence, the solution is $ x=\dfrac{1}{6} .$
