Algebra practice question

Which of the following equations has the solution x = 6?

  1. A. x/2 = 3Correct
  2. B. x + 2 = 6
  3. C. 2x = 6
  4. D. x − 6 = 6

Answer: A. x/2 = 3

6/2 = 3 is true.

Why the other answers are wrong

B. x + 2 = 6
x + 2 = 6 gives x = 4.
C. 2x = 6
2x = 6 gives x = 3.
D. x − 6 = 6
x − 6 = 6 gives x = 12.
