Official Explanation

Answer: E Statement (1) is insufficient. Move the x's to the right side and the b's to the left:
b + b = x + x
2b = 2x
b = x
Unless we know the value of x, we can't find the value of b.

Statement (2) is also insufficient. Move the x to the right side, and the result is b = x. That's the same as (1)! Since both statements are insufficient on their own and identical, the correct choice is (E). There's no way to put them together to answer the question.

Hope it helps :lol:

How about taking X as constant? How do we know X is a variable here?
