Question

please tell its urgent...............

Answer 1

$| |x - 2| - 3| \leq 0 \iff | x - 2 | - 3 = 0 \iff |x -2| = 3 \iff x = 5 \ or\ x = -1.$

The above works because if an absolute value is less than or equal to zero, then it must be zero since absolute values are non-negative by definition.

The final answer is the sum of the solutions so it is 5 - 1 = 4.
