Answer

$\text{the interval } \left( \dfrac{1}{8},2 \right) $

Work Step by Step

Using compound inequalities, the solution to the given inequality, $ -3\lt4(2x-1)\lt12 ,$ is \begin{array}{l}\require{cancel} -3\lt8x-4\lt12 \\\\ -3+4\lt8x-4+4\lt12+4 \\\\ 1\lt8x\lt16 \\\\ \dfrac{1}{8}\lt\dfrac{8}{8}x\lt\dfrac{16}{8} \\\\ \dfrac{1}{8}\lt x\lt2 .\end{array} In interval notation, the solution is $ \text{the interval } \left( \dfrac{1}{8},2 \right) .$
