You can put this solution on YOUR website! Both absolute values are positive quantities. Skipping the logic for the absolute values, These four inequality statements can be made:
which gives ; which gives ; which gives ; which gives ;
and obviously from the original inequality, .
You find at x=4 or at x=7 that the inequality is false. This is in agreement with the separate solutions found as indicated.
Checking the interval between 4 and 7, the inequality is found false.
The inequality is found true for any or any .
