Question

Im 100% sure it is either A or B...

Answer 1

Two systems of equations are shown below:
System A:
2x + y = 5
-4x + 6y = -2

System B
-10x + 19y = -1
-4x + 6y = -2


Which of the following statements is correct about the two systems of equations?
They will have the same solutions because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.

They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 3 times the second equation of System A.

The value of x for System B will be –5 times the value of x for System A because the coefficient of x in the first equation of System B is –5 times the coefficient of x in the first equation of System A.

The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding –12 to the first equation of System A and the second equations are identical.

Answer 2

do u want answer or help?

Answer 3

ummm both lol

Answer 4

lol :)

Answer 5

ok hold on:)

Answer 6

*waits*

Answer 7

did you find the solutions so you can compare the steps taken?

Answer 8

ok i did math for both of them and both are y=1 x=2

Answer 9

the solutions are the same

Answer 10

yeah

Answer 11

i already did tht step

Answer 12

thats why i said its either a or b

Answer 13

so then lets see hmmmm

Answer 14

ok im 14 and going to 9th and im answering questions besides ur questions beyond my grade level: P

Answer 15

kool!

Answer 16

umm i would love to say its b but let me check again

Answer 17

its B.

Answer 18

yay i was right

Answer 19

Ok ok Thanks @Nikato

Answer 20

if you follow the wording for B
2x+y=5
+3(-4x+6y=-2)
----------------

you get the first equation of B which is -10x+19y=-1

Answer 21

but if you do A, you get somethign else

Answer 22

well i did what i could :P : ) n_n

Answer 23

That was what i was attempting to do but i didnt get anywhere xD

Answer 24

Thanx again

Answer 25

no problem

Answer 26

is this still open because you need to know why the answer is B?

Answer 27

no it was just cause i was too lazy to close it lol @triciaal
