Example 7: Solving Linear Inequalities

Step-by-step worked example for this lesson track.

Problem

Find the boundary for 7x4<52\text{Find the boundary for }-7x-4<52

1. Recognize Pattern

ax+b<cx<cbaax+b<c\Rightarrow x<\frac{c-b}{a}

2. Apply Method

7x8<20x<47x-8<20\Rightarrow x<4

3. Conclude

x>8x>-8

Final answer

x>8x>-8
