I need sombidy to show meh the steps how to solve multistep inequality

alones (alones):

Solve the inequality 12x < 22 + x. I have no idea

OpenStudy (anonymous):

awnsers

OpenStudy (anonymous):

?

alones (alones):

whaa??

OpenStudy (anonymous):

what are your awnsers

alones (alones):

x < 1/2 x > 1/2 x < 2 x > 2

OpenStudy (anonymous):

c

OpenStudy (anonymous):

c

OpenStudy (anonymous):

i promise

alones (alones):

geez guys i'm asking the steps

OpenStudy (anonymous):

well you got the awnser ;)

Nnesha (nnesha):

lets change the inequality sign to an equal for a sec 12x=22+x do you know how to solve for x ?

alones (alones):

umm yeah so far i got x=2

Nnesha (nnesha):

how did you get that what was your first step ?

alones (alones):

well i isolated 11x =22

Nnesha (nnesha):

how did you get 11x ?? :=))

alones (alones):

i ..so i subtracted 12 from 22.. geez i made it more confusing

Nnesha (nnesha):

12-22= isn't 11

alones (alones):

yeah it's 10

Nnesha (nnesha):

\[\rm 12x< 2+x\] to solve for x you need to get all x's term on one side of the inequality sign

Nnesha (nnesha):

so to move x to the left side what would you do ?

alones (alones):

umm..my bad ..i think i should take 12 cuz it's with x and 12x-x?

Nnesha (nnesha):

yep in order to get x to the left side you should subtract x both sides and remember x is same as 1x so 12x-x <22 now simplify combine like terms

alones (alones):

oh i actually don't know

Nnesha (nnesha):

combine like terms 12x-x= ????

alones (alones):

12x-x(1) will be 11 O_o i understand ,now i see where you get 11

alones (alones):

wait so what is my next step @Nnesha

Nnesha (nnesha):

right so 11x<22 now to isolate x how would you get rid of 11 ?

alones (alones):

so i think umm..wait how do i get rid of x??

Nnesha (nnesha):

you need to keep the x at left side to solve for x you should move 11 to the right side remember we need x itself at left side

Nnesha (nnesha):

it's 11 times x in order to cancel out the 11 what would you do ? would add 11 subtract divide or multiply ?

alones (alones):

i guess i 'l take 2

Nnesha (nnesha):

what do you mean ?

alones (alones):

11x<22?

Nnesha (nnesha):

yes after subtracting x both sides we get 11x < 22

alones (alones):

so i guess it should be 2??

Nnesha (nnesha):

how did you get 2? how did you cancel out the 11 ?

alones (alones):

cuz 2*11 isn't it's 22

Nnesha (nnesha):

remember it's `11 times x` to cancel out 11 you should do opposite of multiplication

Nnesha (nnesha):

that's correct (when u know the answer choices )

alones (alones):

ummm i a :/ctually didn't look thrue answer choices

alones (alones):

yeah i guess it's C

alones (alones):

thx @Nnesha very much>3!!now i can solve another one on my own!!

Nnesha (nnesha):

yes but 11x<22 you should divide both sides to cancel out 11 and remember when we divide or multiply by negative sign we must flip the inequality sign for example \[-2x \color{Red}{<}6 \] to solve for xx you should divide both sides by `-2` \[x \color{reD}{>} -3\] bec i divided both sides by negative number is i flipped the fraction `<` to `>`

Nnesha (nnesha):

np!

alones (alones):

@Nnesha >3
