Answer

$\text{the interval }\left( 6,12 \right) $

Work Step by Step

Using the properties of inequalities, then, \begin{array}{l} 0.3\lt 0.2x-0.9\lt1.5\\ 3\lt 2x-9\lt15 \text{...multiply all sides by 10}\\ 12\lt 2x\lt24\\ 6\lt x\lt12 .\end{array} Hence, in interval notation form, the solution is $ \text{the interval }\left( 6,12 \right) $.
