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

if you plug in for y. x should equal 2

- anonymous

The answer I got was C

- anonymous

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

- Venomblast

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

- Venomblast

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

- anonymous

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

- Venomblast

hehe thanks :)

- anonymous

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

- Venomblast

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

- anonymous

Then which would be the answer is what I'm asking...my error

- anonymous

:(

- Venomblast

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

- anonymous

I told you the answer I got was C

- Venomblast

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

- anonymous

It's fine love

- 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

- anonymous

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

hehe :) im flattered :)

- anonymous

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

- 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

- anonymous

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

- Venomblast

hehe it cool. i can help :)

- anonymous

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

- anonymous

I'm very very very scared

- Venomblast

why? math test?

- anonymous

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

- Venomblast

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

- anonymous

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

- Venomblast

do people judge you at this site?

- anonymous

I've gotten very negative feedback a few times

- anonymous

Cyber bullying... you know how that goes

- Venomblast

in this site?!?!?!

- anonymous

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

- Venomblast

really.. i thought this was an peaceful site.

- anonymous

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

- Venomblast

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

- anonymous

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

- anonymous

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

- Venomblast

12:54 am :D it alright

- anonymous

You're an hour ahead of me

- Venomblast

you live in Central time right?

- anonymous

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

- Venomblast

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

- anonymous

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.

- Venomblast

- anonymous

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

- Venomblast

- anonymous

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

- Venomblast

hmmm. im curious now lol

- anonymous

;)

- anonymous

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)

- Venomblast

that one whole equation?

- Venomblast

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

- anonymous

yes

- anonymous

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

- Venomblast

lol i got this

- anonymous

into three rather***

- anonymous

I have faith in YOU;)

- Venomblast

is that a 2x or .2x?

- anonymous

huh?

- Venomblast

on the beginning of the question

- anonymous

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

- Venomblast

what math course are you taking?

- anonymous

Algebra

- anonymous

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

- Venomblast

the answer is A

- Venomblast

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

- Venomblast
