Question

solve the system using elimination.
2x+6y=-12
5x-5y=10

a.(2,1)
b.(0,-2)
c.(-2,0)
d.(1,2)

Answer 1

okay smart one so first

Answer 2

lol dont be mean
"noodles"

Answer 3

stfu anyways so we will use elimination and since 2 and 5 (x values) are easier than 6 and 5 to find a common factor for

Answer 4

so 2 and 5 the lowest you can get is 10 because they both go into ten evenly

Answer 5

Do you got notes on this? and what class is this for like geometry or ..?

Answer 6

okay now we are working with this

Answer 7

now we can solve for y because both x's can cancel each other out

Answer 8

to get rid of x you need to subtract changing all further signs of the equation

Answer 9

please speak english lmao

Answer 10

to make the letter x go away so we know what the letter y is we need to change adding to subtracting and subtracting to adding

Answer 11

better smart one ?

Answer 12

that then gives you 40y=-80

Answer 13

when you simplify that its y=-2

Answer 14

so we know that y is -2

Answer 15

b?

Answer 16

now to find x we need to plug the y value back into the equation so you see how they gave you two equations you can pick either one i suggest picking the one with the lowest numbers so

Answer 17

noodles stop BEING SO SMART

Answer 18

the answer is B right?

Answer 19

so to make sure we will use 5x-5y=10

Answer 20

dude stop getting your panties in a twist we need to check

Answer 21

lmao oooops sowwy

Answer 22

anymfways plug y into the problem so 5x-5(-2)=10 then simplify that by first multiplying then moving like terms to opposite sides of the equal sign

Answer 23

ENGLISH MF

Answer 24

miss fujiwara please speak english
i dont understand math language

Answer 25

so 5x+10=10 so 5x=10-10

Answer 26

that is basic math im sorry i dont speak stupid

Answer 27

lol you kinda do

Answer 28

so 5x=0 so x=0 therefore giving you B

Answer 29

you're welcome butt face

Answer 30

but you like my butt face so stfu
