Example: Solving and Graphing 6x3<96x - 3 < 9 and 2x+932x + 9 \geq 3

To solve the compound inequality 6x3<96x - 3 < 9 and 2x+932x + 9 \geq 3, begin by solving each inequality. For the first, adding 33 gives 6x<126x < 12, which simplifies to x<2x < 2. For the second, subtracting 99 gives 2x62x \geq -6, which simplifies to x3x \geq -3. Graphing x<2x < 2 results in shading to the left of an open parenthesis at 22, while graphing x3x \geq -3 results in shading to the right of a bracket at 3-3. The final solution is the overlapping region, which spans from 3-3 up to 22. In interval notation, this is written as [3,2)[-3, 2).
