Data Sufficiency (DS) | Re: Does x=100?

Statement 1 ---> y=0 satisfy the equation, thus x may or may not be 100.
NOT Sufficient

Statement 2 ----> x >0 but still no information about x being 100.
NOT Sufficient

1 & 2 combined ---> still y= 0 satisfies the equation and x can be anything (also x>0)
Hence insufficient

E is the correct option
