algebraWhich inequality has NO solution?
A
B
C
D
Correct Answer: B
Choice B is the correct answer. Some inequalities lead to contradictions when simplified.
- Simplify: Subtract from both sides:
- Result:
- Contradiction: This is FALSE, so no value of satisfies this inequality
?�� Strategic Tip: When variables cancel and you're left with a false statement (like ), the inequality has no solution.
Choice A is incorrect because subtracting gives , which is ALWAYS true (all real numbers are solutions). Choice C is incorrect because this simplifies to , which is true, so all real numbers work. Choice D is incorrect because subtracting gives , always true.
