What is the value of x ?
Statement 1) x^2 + x -6 = 0 => (x-2) * (x+3) = 0 so x can be 2 or -3. Not Sufficient.
Statement 2) x cannot be determined as value of y we don't know. Not Sufficient.
Combining the two statements, from Statment 2) we can see x has to be +ve. So using statement 1) x can take only one value = 2
Sufficient . option C)
Never Give Up !!!
