Best ResponseYou've already chosen the best response.0I haven't done many problems like this before, what part should I do first?

Best ResponseYou've already chosen the best response.0start by subtracting 5 from both sides so that you get the x by itself

Best ResponseYou've already chosen the best response.0Ok so 4/5x < 2

Best ResponseYou've already chosen the best response.0actually, doing it that way is going to make it more complicated than it needs to be ... one moment

Best ResponseYou've already chosen the best response.0actually, that ended up being the quickest way ... but subtracting from both sides leaves you with 4/5x < 8

Best ResponseYou've already chosen the best response.0;P I always get mixed up with that even though I've gone over it a million times

Best ResponseYou've already chosen the best response.0ok, right now with the equation like it is (4/5x < 8) ... you know "one" of the answers is zero because, well just because ... I forget why I just know it's true so just trust me and someone else who's taken math in the past decade will chime in in a bit to tell you

Best ResponseYou've already chosen the best response.0ok so what should you do next?

Best ResponseYou've already chosen the best response.0But, because they're tricky there's another answer too!

Best ResponseYou've already chosen the best response.0next, multiply both sides by 5x to get that 5x out of the denominator

Best ResponseYou've already chosen the best response.0ok so it would be 4x < 40 right

Best ResponseYou've already chosen the best response.1\[4 < 3(5x+5)\]

Best ResponseYou've already chosen the best response.0because \[\frac{ 4(5x) }{ 5x } = 4\] and \[8 (5x )= 40x\]

Best ResponseYou've already chosen the best response.1It's important to note, if this is (4/5)x + 5 < 3 or 4/(5x) + 5 < 3 These are not the same.

Best ResponseYou've already chosen the best response.0@californiagirl55 my last equation should have had 4 < 40x (with < not =)

Best ResponseYou've already chosen the best response.0@qpHalcy0n has said the smartest thing in here thusfar ... I've been solving it as if the equation was \[\frac{ 4 }{ 5x } + 5 < 3\] And, @jiteshmeghwal9 is obviously answering it as if the question was \[\frac{ 4 }{5x + 5 } < 3\] which are completely different things

Best ResponseYou've already chosen the best response.0grrr except I left off the negatives on the threes

Best ResponseYou've already chosen the best response.1so what is the right question @RoamingBlue ??????/

Best ResponseYou've already chosen the best response.0I have no idea *grins* wasn't my question to start with :D

Best ResponseYou've already chosen the best response.0But if you solve it going down the path I was on you end up with 4 < 40x then 4/40 < x or 1/10 < x < 0 as the final solution
