How does a 99 rated mathlete not know how to do system of equations O.o

Well when you haven't done math in a while u forget things.....

|dw:1442268783821:dw|

|dw:1442269218613:dw|

wait why did u use 1 and 2

loads of ways to do these
eg
|dw:1442269699628:dw|

can i ask , do you work on the OS website??

whats the easiest way?
can u do in equation form cause the drawing is losing me

do i work on the website?

yes

what does that mean?

are you part of the OS team?

Oh yes...

so you code this site?!

OK!!

But what if its x+3y=-9
does 3y become positive cause u move it?

if
x + 3y = -9
then
x = -3y - 9

because
x+3y-3y = -9-3y

so i got
6(3y-9)+y=3
18y-54+y=3
+y +y
19y-54=3
+54 +54
19y=57
y=3

so now u plug it into the x too get x right?
x-3(3)=-9
x+9=-9
-9 -9
x=-18
so we got
(-18,3)

??

if you know that y = 3, plug that into one of the original equations to find x

eg, if
x - 3y = -9
what is x
if y = 3

or if 6x + y = 3
what is x
if y = 3??

you plug it into the
x-3y=-9 right?

into either, you want to know when they meet

it says -18,3 is wrong

wait don't i need another point?

i thought we had agreed 0, 3 ?!?!

as in x = 0

and y = 3

OOHOHOHO i did it wrong ok so i need another set of points to connect it.

indeed you might!
gtg

So how do i get it?

Its ok

are you meant to solve by either substitution or elimination?

Graphing them

i got the answer 0,3 just need another point

Yea but thats only one point need 2 for a line

hmmm one sec

ok :D

here use this i did another question
x-3y=-3
3x+y=1
i got (0,1)

..is that another one?

Yea i just change questions
i got 0,1 but need another point

hmmm thought you were supposed to just graph them?

Yea it say
solve the following system of equation by graphing them

well... I'd just graph them then :)
lemme do a quick table

ok thanks

wait do we just do the
x|y thing and put 0 for x and ory?

|dw:1442273690049:dw|
like that?

yeap
to make a line, all you need is 2 points
so just pick two random "x" to get two "y"s

OHH so
|dw:1442273743049:dw|

other is
0,3 2,0

where did u get they -3 from?

x-3y=-3 <---
3x+y=1

is this correct
(0,3) (-9,0)
and
(0,3) (2,0) ?

hmmm 0, 3 is not, -9,0 isn't either

x =0
x -3y=-3
0-3y=-3
y = (-3)/(-3)
y =1

x-3y=-9
-3y=-9
y=1/3
x-3y=-9
x=-9

x=-9
(-9)-3y=-3
-3y=-3+9
-3y=+6
y=(6)/(-3)
y=-2

wait this is confusing me
dont u put 0 for them?

wel... you said it was
x-3y=-3
3x+y=1
but now you seem to have changed it some

OHOHOHO I've been doing the wrong problem... :D KML

I WAS LOOKING AT THE QUESTION LOL

i got
(0,1) (-3,0)
and
(0,1) (3,0)

D: it says my answer is wrong...
i did the x|y thing

check yours PEMDAS I'd think

OHH my friend told me to use y=mx+b

why?
aren't you trying to solve the system
x-3y=-3
3x+y=1
?
or is that not the question?

yes by graphing it thou but i did it and getting it wrong D:

wait can u try thing one
x-2y=-2
4x+y=1

were you trying to write in y=mx+b form to graph the lines to find the point ?

yea i was using that

ok well try writing x-2y=-2 in that form

2y=x+2 right?

yea i got
y=1/2x+1

then u graph it by going to (0,1) then rise over run

yea
we got 0,1 then rise over run -4/1

yea 0,1 is the slope so we go down 4 and move 1 to the left right?

Oh right 1 sorry my friend told me left....

OMG your the best :D

can u help with one more but this one is substitution

sure

one more then I have to roll my croissant dough

ok :D
4x+y=24
y=2x

replace first y with (2x)
solve 4x+2x=24 for x

don't you reverse it like y=4x+24 and plug into x
y=2(4x+24)

wait how did u get 4x+2x=24

\[\color{red}{y=2x} \\ 4x+\color{red}{y}=24 \\ \\ 4x+\color{red}{2x}=24\]

I replaced y with 2x because one of the equations said y=2x

Wait i understand igtg thanks for the help

k peace
