Final answer:
After substituting x = 9 into the given equations, none of the options A, B, C, or D resulted in a true statement. There might be an error, as no provided equations have x = 9 as their solution.
Step-by-step explanation:
To find which equation has the solution x = 9, we can substitute this value into each of the given equations and see which one results in a true statement.
- A) -x + 2 = 7: If we substitute x = 9, we get -9 + 2 = 7, which simplifies to -7 = 7. This is not true, so equation A is not correct.
- B) 32x - 12 = 232: Substituting x = 9 gives us 32(9) - 12 = 232, which simplifies to 288 - 12 = 232. This is not true because 276 ≠ 232, so equation B is not correct.
- C) 8 - 4x = -24: Substituting x = 9, we get 8 - 4(9) = -24, which simplifies to 8 - 36 = -24, and finally -28 = -24. This is not true, so equation C is not correct.
- D) 32 x - 8 = -2: Substituting x = 9, we get 32(9) - 8 = -2, which simplifies to 288 - 8 = -2. This is not true because 280 ≠ -2, so equation D is also not correct.
After testing all equations, we discover that none of the options A, B, C, or D yield a true statement when x = 9. Therefore, there appears to be an error as none of the provided equations have x = 9 as a solution. It is important to double-check the original equations to ensure they have been copied correctly.
