What is the value of x?

[1] (3/2) x + y = 3.

[2] (2/3) y + x = 2.

Obviously (1) and (2) alone are not sufficient to answer the question.
Next combine and check.
[1] = (3/2)x + y = 3.
Multiply this whole equation by 2/3.
So we get x + 2/3y = 2, which is same as [2] and hence not sufficient.

The correct answer is (E).
