I also agree wity Murti's solution, except for the conclusion.
Given y >= 0
From #2. -y >= |x-3|
|x-3| -- Absolute value -- is always +ve or 0
-y >=0 & y >=0 can only be possible if y = 0.
Hence |x-3| = 0 or x = 3 SUFF.
From #1 y <=|x-3| x & y can take any value as long as 0=<y<|x-3|
INSUFF to find x.
