multiply the number outside for example -3(a +4) would be -3*a + 4*-3 +8a < 13 that should be the first step... add like terms are u able to work the problem out from here?

OpenStudy (anonymous):

im confused

OpenStudy (anonymous):

ok do understand -3a +(-12) +8a < 13

OpenStudy (anonymous):

wait wait wait i got it so next i do -3 plus 8a to get 5a Plus -12 <12

OpenStudy (anonymous):

*13

OpenStudy (anonymous):

do i add 12 to 13 or subtract?

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

so its like ur making the one side 0 and moving what u made the one sid 0 and adding that number to other side.

OpenStudy (anonymous):

yes what subtract or add

OpenStudy (anonymous):

well ur making -12 + a number say x = 0 so -12+12 = 0 on left side then moving that x number u used to the other side meaning 13 + 12 = 25

OpenStudy (anonymous):

a<5

OpenStudy (anonymous):

well u get 5a < 25 ?

OpenStudy (anonymous):

ya

OpenStudy (anonymous):

can u help with the next one? i will leave u alone after

OpenStudy (anonymous):

so ur answer to the first one was?

OpenStudy (anonymous):

A<5

OpenStudy (anonymous):

close but no

OpenStudy (anonymous):

?? why

OpenStudy (anonymous):

no i'm sorry my bad its a < 5

OpenStudy (anonymous):

oh ok haha can u help with the next one down

OpenStudy (anonymous):

see if i make silly mistakes

OpenStudy (anonymous):

haha so can u help

OpenStudy (anonymous):

with the next one down

OpenStudy (anonymous):

what do u think u need to do first

OpenStudy (anonymous):

24 - 4

OpenStudy (anonymous):

ok that's good

OpenStudy (anonymous):

and now im stuck

OpenStudy (anonymous):

but should be 24 + 4 or -24 -4

OpenStudy (anonymous):

oh so 28

OpenStudy (anonymous):

what do u do with the x?

OpenStudy (anonymous):

add to get 7?

OpenStudy (anonymous):

wait x is 7!

OpenStudy (anonymous):

right???

OpenStudy (anonymous):

now it should be written like 28 - 3x = 4x so just do same thing except move the -3x to the other side

OpenStudy (anonymous):

wait x is 4

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

u are correct

OpenStudy (anonymous):

X is 4??? really?? wwowowowo

OpenStudy (anonymous):

if u had -5a < -25 what do u think the answer would be

OpenStudy (anonymous):

lot of people miss this cuz of a rule

OpenStudy (anonymous):

a>5

OpenStudy (anonymous):

yes good job

OpenStudy (anonymous):

so my answers were right?

OpenStudy (anonymous):

what was ur 3 problem answer

OpenStudy (anonymous):

im still working on it

OpenStudy (anonymous):

one sec

OpenStudy (anonymous):

dont leave yet

OpenStudy (anonymous):

a>2

OpenStudy (anonymous):

are u sure recheck ur work?

OpenStudy (anonymous):

its wrong?

OpenStudy (anonymous):

did u get 5a - 2 > 6 - 3a

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

and then 2a -2>6

OpenStudy (anonymous):

oh is a 4?

OpenStudy (anonymous):

if u move the -3a to other side so ur add 3a + 5a gets u 8a

OpenStudy (anonymous):

so whats a im confused?

OpenStudy (anonymous):

so when u move the -2 to the other side it will be 2 u get 8 so then 8a> 8

OpenStudy (anonymous):

so a > 1

OpenStudy (anonymous):

Thanks so much for ur help

OpenStudy (anonymous):

your welcome i hope u understand it better
