- Conclusion: There is no value of that makes this true.
?�� Strategic Tip: If variables cancel and the remaining statement is false (e.g., ), there is NO solution. If true (e.g., ), the solution is All Real Numbers.
Choice B is incorrect because the resulting statement is false. Choice C is incorrect because it assumes variables don't cancel. Choice D is incorrect because it assumes variables don't cancel.
