Hi guys.. I would like a simple explanation as of to how to get the solution set of an inequality; Please explain using this example: 4x+5 < 5x-9 Thanks!

Move all the x's to one side. Move all the numbers to the other side. Eg. (Just note that in inequalities when you divide or multiply by a negavive number you have to switch the direction of the inequality)
Thanks, that inequality solution set is quite straight forward..But when I hit this one in the text book..I was a bit confused, could you perhaps shed some light on it: -2 ≦ x+1≦3 Thanks a lot!!
It's pretty much the same thing, just recall basic algebra: To get the 2 to the other side, we add 2 to both sides: It's the exact same thing here with this inequality: Subtract 1 from all parts: So we get:
