How would I solve r>3 or r<-2 ? I'm doing "Solving combined Inequalities".

It's already pretty much solved. r is any real number which is not a member of the closed interval [-2,3]

That is not an equation. Do they need to be combined?
-2 > r > 3

ok, r is greater than 3 or r is less than negative 2. there is no solution to that. There is no number that is both greater than three and less than negative two. The only wild card here is the word or---and I haven't a clue what that means. Sorry. Perhaps this is a trick question?

I think that means everything between -2 and 3 are not correct for r

I don't think this has a solution. If r is greater than 3 it cannot be less than -2. Have you copied something wrong?

What style of answer do you need? You can't simplify that any more: you have the union of two disjoint areas of the number line. Draw the graph ... see?
