I haven't done many problems like this before, what part should I do first?

start by subtracting 5 from both sides so that you get the x by itself

Ok so 4/5x < 2

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

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

RoamingBlueBest ResponseYou've already chosen the best response.0
because 3 5 = 8

;P I always get mixed up with that even though I've gone over it a million times

ok, 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

californiagirl55Best ResponseYou've already chosen the best response.0
ok so what should you do next?

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

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

californiagirl55Best ResponseYou've already chosen the best response.0
ok so it would be 4x < 40 right

\[4 < 3(5x+5)\]
 one year ago

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

It's important to note, if this is (4/5)x + 5 < 3 or 4/(5x) + 5 < 3 These are not the same.

@californiagirl55 my last equation should have had 4 < 40x (with < not =)
 one year ago

RoamingBlueBest 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

grrr except I left off the negatives on the threes

jiteshmeghwal9Best ResponseYou've already chosen the best response.1
so what is the right question @RoamingBlue ??????/

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

RoamingBlueBest ResponseYou've already chosen the best response.0
But 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
