What is the source of this question? It does not seem to be a reliable source. The answers from each statement must be the same; however, it is not.VJesus12 wrote:2A + 2B + 18 = 0, what is B?

(1) A = B
By replacing the value of A = B in the equation 2A + 2B + 18 = 0.
2A + 2B + 18 = 0 => 2B + 2B + 18 = 0 => 4B = -18 => B = -9/2. Sufficient.
(2) A = 3
By replacing the value of A = 3 in the equation 2A + 2B + 18 = 0.
2A + 2B + 18 = 0 => 2*3 + 2B + 18 = 0 => 4B = -18 -6 => B = -24/4 = -6. Sufficient.
The correct answer: D
Hope this helps!
