Step-by-step solution

To solve the inequality x5>11\left|x-5\right| > 11, we first apply the property of absolute values:

  • If A>B\left|A\right| > B, then A>BA > B or A<BA < -B.

Therefore, for x5>11\left|x-5\right| > 11, we have two cases to consider:

  • Case 1: x5>11x-5 > 11
  • Case 2: x5<11x-5 < -11

Let's solve each case separately:

Case 1: x5>11x-5 > 11

Add 5 to both sides to isolate xx:
x>11+5x > 11 + 5

This simplifies to:

x>16x > 16

Case 2: x5<11x-5 < -11

Add 5 to both sides to isolate xx:
x<11+5x < -11 + 5

This simplifies to:

x<6x < -6

Thus, the solution to the inequality is:

x>16x > 16 or x<6x < -6

Comparing this result with the given answer choices, the correct one is:

x>16 x>16 o x<6 x<-6

Therefore, the solution to the problem is x>16x > 16 or x<6x < -6.

Final Answer

x>16 x>16 or x<6 x<-6
