Question: Is 5-2x Greater than -1?

Comment on Is 5-2x Greater than -1?

Like the last video if x was negative wouldn't the target question be x<3 ora x>-3?

I'm not sure which video you're referring to. Can you be more specific?

But for the second statement, x could be less than 2, but x < 3 defines that x could be less than 3 which includes 2 also so how it's sufficient unless x ≤ 2?

Be careful. The rephrased target question (Is x < 3?) isn't telling us that x is less than 3; it's asking us a question: "Is x < 3?"

We don't know whether x < 3. In fact, that's the target question we're trying to answer.

Statement 2 tells us that x < 2
Does this information help us determine whether or not x < 3?
Yes.
If it is the case x < 2, then we can be certain that x < 3

Does that help?

Cheers,
