What is the value of x?
(1) 3(x-1) = y+3x
(2) (x+2)(y+3) = 0
3(x-1) = y+3x
=> 3x- 3 = y + 3x
y = -3
We don't know x so NOT SUFFICIENT
(x+2)(y+3) = 0
=> x= -2 or y =-3 or both x=-2 and y=-3
But we are still not sure as if y=-3 then x need not be equal to -2
SO, NOT SUFFICIENT.
Taking STAT1 and STAT2 together
we are still not sure as y=-3 for sure then x need not be equal to -2
So, Answer will be E
Hope it helps!
