Answer

$(-\infty,1)\cup(5,\infty)$. The graph is shown below.

Work Step by Step

The given compound inequality is $\Rightarrow 3x\lt3$ or $2x\gt10$. Solve each inequality separately. $\Rightarrow 3x\lt3$ or $2x\gt10$. $\Rightarrow x\lt1$ or $x\gt5$. First graph then take the union of the solution sets of the two inequalities. The graph is shown in the image file. We can write the compound inequality. $x\lt1$ as $(-\infty,1)$ and $x\gt5$ as $(5,\infty)$ The union is $(-\infty,1)\cup(5,\infty)$.
