What is the value of x?

(1) 3(x-1) = y+3x

(2) (x+2)(y+3) = 0

STAT1:
3(x-1) = y+3x
=> 3x- 3 = y + 3x
y = -3

We don't know x so NOT SUFFICIENT

STAT2:
(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

Hope it helps!

Even more straight

1) y= -3 we do not know X insuff

2) if look at this one (x+2)(y+3)=0 if we have for instance y=-3 then we have zero, so x can be anuthyng but we have ALWAYS zero

Combien gives us the same situation.

Statement 1 tells us that y = -3. But there's no info on x. Not sufficent
Statement 2 tells us that either y = -3, or x = -2. Not sufficient.

By combining both statements we still cannot determine what the value of x is. We know y = -3 which leaves x to be any number.
