Question #N680
The equation $2x + 3 = 12$ is equivalent to which of the following equations?
A. x + 3 = 6
B. 2x = 9
C. x = 9/2
D. x = 6
Correct Answer is: B
Subtracting 3 from both sides of the equation $2x + 3 = 12$ gives us $2x = 9$. Therefore, the equation $2x + 3 = 12$ is equivalent to the equation $2x = 9$.
