(Section 0.12: Solving Inequalities) 0.12.2 Example 1 (Solving a Linear Inequality) Solve ± 3 x > x + 8 . § Solution Method 1 ± 3 x > x + 8 Now subtract x from both sides. ± 4 x > 8 Now divide both sides by ± 4 . We must then reverse the direction of the inequality sign. x < ± 2 The solution set … in set-builder form is: x ± ± x < ² 2 {} , or x ± ± : x < ² 2 {} … in graphical form is:
