Best ResponseYou've already chosen the best response.1Bro, if you multiply or divide by a negative number, it doesn't matter. You have to switch signs.

Best ResponseYou've already chosen the best response.1x+5 > 18 Now that gives us a valid equation to work with since distance (being positive) can be greater than a negative number.

Best ResponseYou've already chosen the best response.0ok so  x+5  > 18. now you subtract 5 right? so thats x > 23. thats not a choice

Best ResponseYou've already chosen the best response.0yes, like u said before the solution should be x<13 or x>23 (dont use word "and")

Best ResponseYou've already chosen the best response.0yea, all real number :)  multiply by abs number always be negative, right ? because abs number must be positive

Best ResponseYou've already chosen the best response.1Yeah, this is the type where you cannot solve for x by using normal algebra methods. You just have to look at it and realize distance will always be greater than a negative number
