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 texas instruments 83 plus silver edition

10. robinfr93

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

11. robinfr93

:P

12. robinfr93

Thats the Spirit!!

13. elizabeth.a.fairweather

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

14. robinfr93

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..

15. robinfr93

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

16. elizabeth.a.fairweather

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

17. robinfr93

BINGO!!

18. elizabeth.a.fairweather

then what do i do

19. robinfr93

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..

20. robinfr93

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

21. robinfr93

oh oh

22. robinfr93

sorry

23. robinfr93

i made a small mistake der

24. robinfr93

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

25. robinfr93

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

26. robinfr93

3x<-9 that is x<-3

27. elizabeth.a.fairweather

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

28. robinfr93

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

29. elizabeth.a.fairweather

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

30. robinfr93

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

31. robinfr93

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..

32. robinfr93

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

33. robinfr93

Elizabeth did you get it??

34. elizabeth.a.fairweather

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

35. elizabeth.a.fairweather
