Question

Solve by the elimination method.
0.3x-0.2y=4
0.2x+0.3y= -37/17

Answer 1

u did this b4 too.

Answer 2

x = 32.7

y = -29

Answer 3

(32.7,-29) ?

Answer 4

Yes!

Answer 5

ok. I did do a similar one before. that answer was a fraction though/

Answer 6

id rather ti83 it :)

Answer 7

huh?

Answer 8

o.O

Answer 9

amistre, is busy incresing his xp! ;)

jk

Answer 10

lol

Answer 11

:) gotta gain up lost points from the outtage lol

Answer 12

the ti83 gives me decimals; and this thinl looks to turn mean in the end

Answer 13

it close to (6,-11) :) if that helps

Answer 14

i fthis is on a program; they give any options?

Answer 15

lol so the answer is decimals? I juist want to make sure it accepts the answer

Answer 16

the answers are fractions for exact form; but my calc only gives me the decimals

Answer 17

*10; 0.3x-0.2y=4
*10; 0.2x+0.3y= -37/17

3x-2y=40
2x+3y= -370/17 ; *17


3x-2y=40
34x+51y= -370 this looks better and is prolly more doable

Answer 18

it says simplify your answer. Type an ordered pair. Use integers or fractions for any numbers in the expression.

Answer 19

sounds like mathlab stuff

Answer 20

LOL

Answer 21

haha.

Answer 22

3x- 2y= 40 ; *34
34x+51y= -370; * -3

102x - 68y = 1360
-102x -153y = 1110
--------------------
221y = 2470

y = 2470/221

cant tell if it simplifies yet :)

Answer 23

y = 190/17

Answer 24

wow...I am going to study over this while you figure it out. There is still x to solve right?

Answer 25

3x - 2y = 40 ; *51
34x +51y = -370; * 2


153x -102y = 2040
68x +102y= -740
-------------------
221x = 1300

x = 1300/221 ; /13 top to bottom

x = 100/17

Answer 26

i think i tripped over myself; gotta dbl chk

Answer 27

i cant get them to match up :/

Answer 28

i see it; i dropped a negative sign lol

Answer 29

that got it lol

Answer 30

x=100/17
y=-190/17

Answer 31

thank you.

Answer 32

yep; hunting down that lost - was a bummer :) everything else was good

Answer 33

I was lost. LOL
