## InsanelyChaotic 3 years ago I'll tell you a secret if you help me? :))))) If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalent to y from the first equation is substituted into the second equation.8x - 2y = 4 4x + 5y = -18 Answer options: 4x + 5(-4x - 2) = -18 4x + 5(4x - 2) = -18 4(-4x - 2) + 5y = -18 4(4x - 2) + 5y = -18

1. Venomblast

bet

2. Venomblast

leave the y by itself

3. Venomblast

well you can solve for y. iof you divide -2 on both side, y should equal -2

4. Venomblast

now plug -2 for y

5. InsanelyChaotic

I have that :)

6. InsanelyChaotic

help me!!!!!!!!!!!:(((((((((((((

7. Venomblast

ok ok lol

8. Venomblast

if you plug in for y. x should equal 2

9. InsanelyChaotic

The answer I got was C

10. InsanelyChaotic

no worries dear :) @iheartfood by the way, I <3 food too!!!

11. Venomblast

so 4(2) + 5(-4(2) - 2) = -18 8+5(-8-2)=-18 8+5(-10)=-18 8-50=-18 -42=-18 FALSE

12. Venomblast

now all you have to do is plug it in for each. dont worry i will help you

13. InsanelyChaotic

awwwww you are sooo sweeeeet!!!!! :))))))))) @Venomblast

14. Venomblast

hehe thanks :)

15. InsanelyChaotic

Can you help me finish the problem with how you were taught so I can refer back to it and learn? :))

16. Venomblast

yea. but i already told you. all you have to do is find what x and y equal and then plug it in.

17. InsanelyChaotic

18. InsanelyChaotic

:(

19. Venomblast

ok the 1st one wont work. i tried the second and still doesnt work

20. InsanelyChaotic

I told you the answer I got was C

21. Venomblast

you did? i didnt get it i think. imaybe i just miss it

22. InsanelyChaotic

It's fine love

23. Venomblast

for C 4(-4x - 2) + 5y = -18 4((-4(-2))-2)+5(-2)+=-18 4(8-2)-10=-18 4(6)-10=-18 24-10=-18 FALSE

24. InsanelyChaotic

OMG I GET IT NOW!!!!!! THANK YOU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! i CORRECTED MY ERRORS

25. InsanelyChaotic

YOURE THE BEST!!!!! SERIOUSLY!!!!!!!!!

26. Venomblast

31. InsanelyChaotic

god you're so sweet! I could hug you xoxoxoxox

32. Venomblast

if you were in NYC lol i can

33. Venomblast

I love to help. I am also going to become a math tutor. paid.

34. InsanelyChaotic

I wish! It being as famous as it is and all :)

35. Venomblast

im really happy you got your solution :).

36. InsanelyChaotic

you'd make a terrific one, seriously... you're so understanding and thorough

37. InsanelyChaotic

you'd make for a great partner

38. Venomblast

awww that was sweet what you said. i feel like taking a snapshot. you being my reference will convince people i am great at math

39. Venomblast

any more questions ?:)

40. InsanelyChaotic

awwwwww! I'd love to tell them great things about your SUPERIOR math skills!

41. Venomblast

hehe :) im flattered :)

42. InsanelyChaotic

I have MANY more unfortunatly, but i don't want to bother you...

43. Venomblast

well im here to help. there no such thing as bothering if your on a site like this. i like helping people even if its for free

44. InsanelyChaotic

you're such a kind being. I like to help people on yahoo answers and elsewhere, but when it comes to math, I have very LITTLE to offer, so I really do appreciate your efforts

45. Venomblast

hehe it cool. i can help :)

46. InsanelyChaotic

The sad part is I'm in a rush... I have so many questions and very little time

47. InsanelyChaotic

I'm very very very scared

48. Venomblast

why? math test?

49. InsanelyChaotic

And I've literally been upset and crying all day. My eyes have been blood shot red.

50. Venomblast

oh :( if this get personal to you, just send me a personal email :) just for your privacy. what happen by the way. :o

51. InsanelyChaotic

you can email me if you want some time :) i have a lot to offer. part of what makes me upset about getting on here, is that people know me for my lack of understanding in math, and that's the only judgement they can make about me, when i'm very intelligent in other aspects

52. Venomblast

do people judge you at this site?

53. InsanelyChaotic

I've gotten very negative feedback a few times

54. InsanelyChaotic

Cyber bullying... you know how that goes

55. Venomblast

in this site?!?!?!

56. InsanelyChaotic

in fact, today I heard that I was "retarded" on here.. it made me feel OH SO WARM INSIDE. not

57. Venomblast

really.. i thought this was an peaceful site.

58. InsanelyChaotic

another time this one lady gave me the hardest time when all I was doing was learning. i could easily say "f you" to learning math, but I try to at least get my answers checked and look for explanations if i'm incorrect

59. Venomblast

yea dont bother with people that has no patience. not worth it, i can make you learn math. i love to help

60. InsanelyChaotic

you're really a great person. I'm not even kidding you.

61. InsanelyChaotic

I don't want to keep you up though... what time is it in NYC?

62. Venomblast

12:54 am :D it alright

63. InsanelyChaotic

You're an hour ahead of me

64. Venomblast

you live in Central time right?

65. InsanelyChaotic

But considering NY is such a lively place, i'm sure you're used to being up late, and yes

66. Venomblast

yea you got that right. the city that never sleep :)

67. InsanelyChaotic

If you help me fast, I'll literally do anything. Time is ticking and i would never want to use someone and make them feel unwanted, but I want and need you right now.

68. Venomblast

69. InsanelyChaotic

i don't even have time for explanations as to why the answer is right. I know that sounds horrible. but I am f******

70. Venomblast

lol take a deep breath and relax lol. you already type fast. that a good start. so tell me the question.

71. Venomblast

from this question or a new question?

72. InsanelyChaotic

hahahahahahaha thank you!!!! ;) i fkn' owe you

73. Venomblast

nah it free of charge :P

74. InsanelyChaotic

I still owe you with something. i'll keep in touch with you and let you in on my mysterious ways

75. Venomblast

hmmm. im curious now lol

76. InsanelyChaotic

;)

77. InsanelyChaotic

1. Solve the following system of equations.2x + 3y - z = 13x + y + 2z = 12x + 2y - 3z = -5 (3, 1, 2) (-3, 1, 2) (3, -1, 2) (3, 1, -2)

78. Venomblast

that one whole equation?

79. Venomblast

let me guess, the 1st column is x the second is y and the last is z?

80. InsanelyChaotic

yes

81. InsanelyChaotic

I think you break it down into two, so you separate it

82. Venomblast

lol i got this

83. InsanelyChaotic

into three rather***

84. InsanelyChaotic

I have faith in YOU;)

85. Venomblast

is that a 2x or .2x?

86. InsanelyChaotic

huh?

87. Venomblast

on the beginning of the question

88. InsanelyChaotic

No period in the beginning, my error 2x + 3y - z = 13x + y + 2z = 12x + 2y - 3z = -5

89. Venomblast

what math course are you taking?

90. InsanelyChaotic

Algebra

91. InsanelyChaotic

I guess you can't help me....

92. Venomblast

93. Venomblast

lol i took calculus and im not even on that class yet

94. Venomblast
