Practice Question
Solve the equation for x: ½ x + 9 = -2/3 x
Answer Choices
- A: x=-9/7
- B: x=-54/7
- C: x=-6
- D: x=-54
Correct Answer: B
Rationale: Add 2/3 x to both sides: ½ x + 2/3 x + 9 = 0. Combine: (3/6 x + 4/6 x) + 9 = 7/6 x + 9 = 0. Subtract 9: 7/6 x = -9. Multiply by 6/7: x = -9 * 6/7 = -54/7. Thus, the correct answer is x=-54/7.
