What have you tried?
Where are you stuck?
for these kinds of problems, you would
divide this into cases where
1. x<1, x=1
3. x>3, x=3
but that problem is weird. even if you put x=1, it's smaller than 5. i think the question's messed up lol
Well, I would not say "messed up". I would just say that the answer to the problem is "there is NO value of x that makes this inequality true."
