Answer:

[tex]-6\leq x\leq 16[/tex]

Step-by-step explanation:

So we have the inequality:

[tex]|x-5|\leq 11[/tex]

Definition of Absolute Value:

[tex]x-5\leq 11\text{ or } x-5\geq -11[/tex]

Note that the sign is flipped in the second case because we multiplied by a negative.

Add 5 to both sides to both equations:

[tex]x\leq 16\text{ or } x\geq -6[/tex]

Merge:

[tex]-6\leq x\leq 16[/tex]

And we're done!
