Step-by-step explanation:
Given
Required
Solve
Start by dividing both sides by 5
Find critical point of the inequality by changing the inequality to equality
Split the above expression
Make x the subject of formula in both
Check the intervals in between the critical points
Set: --- This works in the inequality
Set: --- This doesn't work in the inequality
Set: --- This doesn't works in the inequality
Set: --- This works in the inequality
<em>Hence, the solution is: {x| x > 2 or x < -4}</em>
