Pls post detailed solution
Thanks
Rephrase the question:
x/(y-x) = 1
x = y-x
2x = y.
Question rephrased: Does y = 2x?
Statement 1: |x|= x-y
If x<0, then x-y = -x:
x-y = -x.
2x = y.
If x>0, then x-y = x:
x-y = x
y=0.
If y=0, then x can be any positive value and y ≠2x.
Insufficient.
Statement 2: x³<0.
Thus, x<0.
No information about y.
Insufficient.
Statements 1 and 2 combined:
To satisfy statement 2, x<0.
If x<0 in statement 1, then y = 2x.
Sufficient.
The correct answer is
