6
algebraSolve:
A
B
C
D
Correct Answer: A
Choice A is the correct answer. When a variable term is subtracted, we need to carefully handle the negation.
- Subtract 6: , giving
- Divide by -1: (REVERSE the sign!)
- Simplify:
?�� Strategic Tip: Dividing by -1 (or multiplying by -1) reverses the inequality. Alternatively, you can add to both sides first: , then solve.
Choice B is incorrect because it fails to reverse the inequality when dividing by -1. Choice C is incorrect because it adds 6 and 2 to get 8, using faulty arithmetic. Choice D is incorrect because it combines both wrong value and wrong direction.
