Add 6 to isolate x: Add 6 to both sides of the inequality to isolate x.x−6+6≤3+6
Simplify inequality: Simplify both sides of the inequality. x≤9
Check solution: Check the solution by choosing a value for x that is less than or equal to 9 and substituting it back into the original inequality to see if it holds true.Let's choose x=9.9−6≤33≤3This is true, so our solution seems correct.
