Can someone please help me solve this? I have no idea how to do this. Thanks!
If y>=0, what is the value of x?
1) |x-3| >= y
2) |x-3| <= -y
If y>=0, what is the value of x?
1) |x-3| >= y
2) |x-3| <= -y
First Statement
|X-3|>=Y
as LHS is always a positive number, so depending on the value of Y, it will create many value of X.
Insufficient
Second Statement
|X-3|<=-Y
As Y is always non-negative so -Y is always non-positive. That means |X-3| is always less than or equal to a non-positive number, which is only possible when that number is zero. i.e. Y=0. So X=3
Sufficient
Answer B.
