1. tootie149 Group Title

help

2. tootie149 Group Title

I got -12/25 but this does not work when i plug it in

3. lgbasallote Group Title

is that $\huge -\frac 45 x = \frac 35$

4. tootie149 Group Title

yes, it is how did you type in the fraction?

5. lgbasallote Group Title

try clicking the equation button by the comment box...you should see the fraction command there

6. lgbasallote Group Title

anyway if you multiply both sides by 5 what do you get?

7. tootie149 Group Title

ok i see it now thanks

8. lgbasallote Group Title

welcome

9. tootie149 Group Title

for the -4/5 * 5 =-4 and 3/5*5=3

10. lgbasallote Group Title

yes dont forget x

11. tootie149 Group Title

x=-4/3

12. tootie149 Group Title

wow I get so lost so quick

13. lgbasallote Group Title

it's not -4/3

14. tootie149 Group Title

y, what did i do wrong

15. lgbasallote Group Title

i assume you tried to solve it mentally. that's what you did wrong. do it step by step

16. tootie149 Group Title

ok give me a min

17. lgbasallote Group Title

sure

18. tootie149 Group Title

do i flip the -4/5 when I isolate the x like this -4/5x=3/5 x= 3/5 div -5/4

19. lgbasallote Group Title

$\huge -\frac 45 x = \frac 35$ you start by multiplying both sides by 5

20. tootie149 Group Title

y 5

21. tootie149 Group Title

is it because both of the fraction have 5?

22. lgbasallote Group Title

you multiply both sides by 5 because x has a denominator of 5

23. tootie149 Group Title

ok so this gets rid of the fractions

24. tootie149 Group Title

right ?

25. lgbasallote Group Title

yes. so what does the equation look like after?

26. tootie149 Group Title

-4x=3 ?

27. lgbasallote Group Title

right. so now what would you do?

28. tootie149 Group Title

div both sides by -4

29. tootie149 Group Title

-0.75

30. tootie149 Group Title

x=0.75

31. tootie149 Group Title

32. lgbasallote Group Title

yes that is right. but you should but it in fraction for

33. tootie149 Group Title

-4/3

34. lgbasallote Group Title

form*

35. lgbasallote Group Title

how did you get -4/3? (after i said it wasnt right)

36. tootie149 Group Title

1 1/3 sorry

37. tootie149 Group Title

looked at the wrong part of my paper

38. tootie149 Group Title

1/3

39. lgbasallote Group Title

....what did you get again after you divided by 5?

40. tootie149 Group Title

-4x=3

41. lgbasallote Group Title

so what did you after that?

42. simplicity Group Title

-4x/5=3/5 =>-4x=3*5/5 =>-4x=3 =>x=-3/4

43. lgbasallote Group Title

what did you do*

44. tootie149 Group Title

-3/4

45. tootie149 Group Title

wow I have been typing it upside down

46. lgbasallote Group Title

what were you doing to get -4/3?

47. tootie149 Group Title

forgot to div both sides by -4 and because i can not reduce -3/4 that is my answer

48. lgbasallote Group Title

you need to remember that you divide both sides by the coefficient of x ALWAYS... in this case your coefficient is 4..that's why you divide both sides by 4

49. tootie149 Group Title

because what i do to one side I do to the other

50. tootie149 Group Title

in order to get x alone I div -4x by -4 and I div 3 by -4 also this gives me -3/4

51. godorovg Group Title

guys this problem is simple -4/5x=3/5 take the -4/5 and divide by 3/5 so you have X= -4/5 divided by 3/5 now flip the 3/5 to 5/3 so that is to change the divide to times so now you have -4/5 times 5/3= ??

52. tootie149 Group Title

-4/3

53. tootie149 Group Title

I am so wrong just looked at it

54. lgbasallote Group Title

uhhh what?

55. lgbasallote Group Title

56. tootie149 Group Title

IDK!!!!!!!!

57. tootie149 Group Title

sorry for yelling

58. lgbasallote Group Title

lol

59. lgbasallote Group Title

you have -4x = 3 you said you divide by =4 so what happens if you do that?

60. tootie149 Group Title

the web site wolfram alfa said it is -4/3

61. lgbasallote Group Title

could you post the URL of that wolframalpha?

62. tootie149 Group Title
63. godorovg Group Title

no need that is right -4/3 that is what I got when I worked the problem out as well.look at my post where I went step by step through this problem.

64. tootie149 Group Title

reduced form is 1and 1/3

65. nickhouraney Group Title

nooo

66. lgbasallote Group Title

you told be the problem was $\huge -\frac 45 x = \frac 35$ what you posted in wolframalpha was $\huge -\frac{4}{5x} = \frac 35$ see the difference/

67. lgbasallote Group Title

you told me*

68. tootie149 Group Title

no

69. lgbasallote Group Title

in the first one, the x is in the numerator. In the second one, the x is in the denominator

70. lgbasallote Group Title

so which one is it?

71. godorovg Group Title

what is this again??

72. tootie149 Group Title

the x is off to the side of the side like -4/4(x)

73. lgbasallote Group Title

then like i said -4/3 is wrong

74. lgbasallote Group Title

this is how you type it in wolfram http://www.wolframalpha.com/input/?i=-4%2F5+x%3D3%2F5

75. lgbasallote Group Title

wolfram is very meticulous and choosy so you have to wrie the question properly

76. lgbasallote Group Title

got it now?

77. lgbasallote Group Title

@tootie149 are you still there?

78. TheViper Group Title

$\huge -\frac 45 x = \frac 35$ $$\LARGE{-4x=\frac{3\times5}{5}}$$ $$\LARGE{-4x=3}$$ $$\LARGE{x=\frac{3}{-4}}$$
