Please explain how to get it

well..let's do the first first, alright?

first one*

okay please explain how to get answer i have no idea where to start on any of them ")

\[ x- 3 > -9\]
do you know how to do it when its \((x-3) = -9\)

well i would make the x into -3

you are solving for \(x\)

is that what we have to ??

okay i read it

if you have any problems then ask me..

okay for the first one what do we do??

\[x-3 >-9\]
we are solving for \(x\) why not you try it first?

okay-3 is the answer because -3 times -3 is 9 and 9 is greater than -9 right

what? \(x\) is variabe..not times..

a variable*

i thought were suppose to replace x with number??

looks like you have to solve for \(x\) not substituting..

ohhh k so we add 3 to both sides right?

@SchoolFreak , mini isn't already helping you!

is*

i know

Yes!

thats the answer?

yeah lol

you are basically solving for \(x\) thats all

correct

okay lets try the next one

–2x + 1 ≤ –11

why dont you try and tell me what you get

okay i think the first step is to add 2 to both sides?

think first; why add to 2? since its +1?

just isolate the -2x in the first hand so you wont get confused

okay so then you add 1 to both sides?

yes you subtract because it was a positive in the rhs

–2x + 1 ≤ –11 Okay so now we have -2x ≤ 12

not quite.. whats -11 - 1?

ohhh -12

yes, now you know what to do next

-2x ≤ -12
now we divide both sides by -2 and we have x ≥ 6

yes!

yes

okay let me try this next one all by myself

10 < –3x + 1

alright, if you need help ask me :)

kk

nope..show me what you did

10 < -3x + 1
9 < -3x
-9 > x

you made a small mistake
whats 9/-3?

nope 9/ - 3

like 9 divide by negative 3

-3 is the answer??

yes but dont forget the inequality signs

not quite..the sign is wrong

No because we divide by a negative so we flip the sign

10 < -3x + 1
9< -3x
-3x > 9

understand so far?

why did u turn the equation on the last part

you have to change*

oh i didnt know that

lets not turn the equation then
lets start from 9< -3x

okay then then we dived and we -3 > x

then you still have to change the x for it to be in the front so x> -3

i mean x<-3

ohh k

not really..expand it

the first side first

if we do the first side we will have 2x + 10 right on the left side??

yeah.
i gotta go now. sorry.

noo :(

hopefully someone else can help you..if not i'll be back later :)

okay
