add 3 on both sides.
You'll get -9x >= 54
Divide or multiply both sides by -1..
such as -9x * 1 >= 54*-1
since value of 54 is now negative, so we flip the inequality sign..
therefore 9x<= -54
divide both sides by 9 and solve..
you'll get x <=-6
Hope this helps

yeah sure ypu can..
But you'll be literally insulting the poor machine and its maker by trying to solve such an easy sum..

:P

Thats the Spirit!!

so i know i am supposed to add the two to the seven which is ten and then to the -3x but that stays the same for some reason then i forgot what to do next haha

- anonymous

newho back to the sum -3x -2 > 7
its same as before..
Take the constant terms onright hand side, by contant terms i mean the numerical terms without variables..

- anonymous

just tell me if you understand what i mean by taking term on the right hand side..

- anonymous

taking term not sure of the meaning i would assume take it and add 2 to it

- anonymous

BINGO!!

- anonymous

then what do i do

- anonymous

great now we have reduced the equation to -3x>7
Multiply or Divide both sides by -1
The sign will be flipped as at both the sides we are multiplying by negative 1..

- anonymous

that is 3x <-7
or x<-7/3

- anonymous

oh oh

- anonymous

sorry

- anonymous

i made a small mistake der

- anonymous

well be having -3x>9 since we added 2 on both sides

- anonymous

after multiplying or dividing my negative 1 in this equation well get

- anonymous

3x<-9
that is x<-3

- anonymous

ok so after i take the 2 and add it to 7 to get 9 i also add it to the -3x and then i have -3x>9 then i how do i know if i am to multiply or divide to get the answer x<-3

- anonymous

well it doesnt't matter..
you divide a no by -1 or multiply a number -1 you get the same answer...
get it?

- anonymous

yup i get it the only thing i am still confused about it how you took 3x<-9 and got x<-3 what did i miss haha

- anonymous

we still have a co efficient that is the number that you've along with your variable in 3x<-9 ryt??

- anonymous

what we want is value of just x and not 3x..
So in order to find the value of just x we divide both the sides by 3..

- anonymous

ultimately giving us x<-3 and VIOLA!!!

- anonymous

Elizabeth did you get it??

- anonymous

sorry just one sec i had to do something and havent read it all yet one sec to let me look over it haha

- anonymous

awesome makes so much more sense now k haha im blonde so its just like a turtle learning new skills haha
