Algebra practice question
Which of the following equations has x = 4 as its solution?
- A. 3x − 2 = 10Correct
- B. 3x + 2 = 10
- C. x + 4 = 0
- D. 2x = 4
Answer: A. 3x − 2 = 10
3(4) − 2 = 10.
Why the other answers are wrong
- B. 3x + 2 = 10
- 3(4) + 2 = 14, not 10.
- C. x + 4 = 0
- 4 + 4 = 8, not 0.
- D. 2x = 4
- 2(4) = 8, not 4.
