## anonymous 5 years ago Solve using the addition and multiplication principles 3 1 2 1 _ _ _ - 4 (3x - 2) - 3 < 3

1. anonymous

12x - 8 -3 < 3 12x < 3 + 3 + 8 12x < 14 x < 14/12 x < 7/6

2. anonymous

wow

3. anonymous

do u mind clarfyin

4. anonymous

do u follow that ok?

5. anonymous

no

6. anonymous

You need to use the distributive property and distribute the 4 to the 3x making it 12x and the 4 to the -2 making it -8

7. anonymous

well to be honest i dont know what you mean by the multiplication and addition principles. i know that i've got the right answer but i dont want to confuse you

8. anonymous

o ok thats what the instruction says... i see how u got the bottom what about the top?

9. anonymous

what do you mean?

10. anonymous

they are fractions

11. anonymous

yes i used the distribution principle in my first line

12. anonymous

3/4 1/2 and so on

13. anonymous

You need to get x by itself.

14. anonymous

Then you reduce it.

15. anonymous

sight up so with how jim worked it out thats final? and jim im not goin against just ask

16. dumbcow

write fractions more clearly...1/2 what you wrote is confusing

17. anonymous

It looks right. You can put this into a TI-89 or HP48/50 and have it do it for you.

18. anonymous

it was even more confusing but its identical to the textbook

19. anonymous

its wrote just as that

20. anonymous

i have a Ti-89

21. anonymous

TI-89 does all Algebra for you.

22. anonymous

i had to write it that way cause the parethesis

23. anonymous

You have to to show that you need to distribute.

24. dumbcow

$\frac{3}{4}(3x-\frac{1}{2}) - \frac{2}{3} <\frac{1}{3}$

25. anonymous

yes thats correct cow

26. anonymous

TI-89 can do that.

27. anonymous

OH!, then I might have been wrong.

28. anonymous

how? barley know how to work that calc

29. anonymous

I only did 4 (3x - 2) - 3 < 3

30. anonymous

yes i see

31. anonymous

Find "solve("

32. anonymous

Put in the problem like Cow did.

33. anonymous

then do ",x)

34. anonymous

"

35. anonymous

sightup i have no idea of what ur tryn to say

36. dumbcow

$x <\frac{11}{18}$

37. anonymous

38. anonymous

Another awesome utility to learn is wolframalpha.

39. anonymous
40. anonymous

cow what steps?

41. anonymous

ok sightup ima check it out

42. anonymous

Same steps, distribute, combine like terms and get x by itself. ALWAYS.

43. anonymous

so sightup just as u did do u think u can show work to get this sum that he got

44. anonymous

Let me work it out quick.

45. anonymous

k

46. anonymous

I get the same answer.

47. anonymous

You need to know how tho?

48. anonymous

i went to the sight u gave

49. anonymous

same answer yes but i need to see the work

50. anonymous

ok its like this.

51. anonymous

first thing like i said is distribute.

52. anonymous

9x/4 - 3/8 -2/3 < 1/3

53. anonymous

we are going to move over the - 3/8 -2/3 so it now read like so: 9x/4 < 1/3 + 3/8 + 2/3

54. anonymous

combine like terms.

55. anonymous

9x/4<11/8 is what we get

56. anonymous

just times it now and you get your answer.

57. anonymous

great thanx for showing me that!

58. anonymous

learn to use your TI-89 and you will never have to do algebra again.

59. anonymous

i need lessons um where can i get info on that?

60. anonymous

youtube.com... just type how to ..... ti-89

61. anonymous

o ok kool

62. anonymous

how to solve for 0 ti-89 for example

63. anonymous

or x

64. anonymous

i got to pee ttyl.

65. anonymous

k
