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

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

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
  • anonymous
just tell me if you understand what i mean by taking term on the right hand side..
anonymous
  • anonymous
taking term not sure of the meaning i would assume take it and add 2 to it
anonymous
  • anonymous
BINGO!!
anonymous
  • anonymous
then what do i do
anonymous
  • 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
  • anonymous
that is 3x <-7 or x<-7/3
anonymous
  • anonymous
oh oh
anonymous
  • anonymous
sorry
anonymous
  • anonymous
i made a small mistake der
anonymous
  • anonymous
well be having -3x>9 since we added 2 on both sides
anonymous
  • anonymous
after multiplying or dividing my negative 1 in this equation well get
anonymous
  • anonymous
3x<-9 that is x<-3
anonymous
  • 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
  • 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
  • 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
  • anonymous
we still have a co efficient that is the number that you've along with your variable in 3x<-9 ryt??
anonymous
  • 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
  • anonymous
ultimately giving us x<-3 and VIOLA!!!
anonymous
  • anonymous
Elizabeth did you get it??
anonymous
  • 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
