Question

Choose the equivalent system of linear equations that will produce the same solution as the one given below.
6x + 2y = -6

3x - 4y = -18 (1 point)


A.)12x + 4y = -12
15x = -30

B.)8x + 4y = -4
14x = -10

C.)6x - 8y = -36
-6y = -42

D.)6x - y = -15
3y = 9

Answer 1

Well... we have to solve the first system of equations given before the choices.

Answer 2

ok So as in solve you mean...??

Answer 3

So what does y equal

Answer 4

y =3

Answer 5

Correct, Now you must substitute (3) for y in x = -1/3y - 1

Answer 6

Let me know what you get.

Answer 7

-3??

Answer 8

Close.

Answer 9

Where did you get -3?

Answer 10

wait would it be -2

Answer 11

Now try.

Answer 12

Wait yes!

Answer 13

There you go!

Answer 14

Now we have to solve the others.

Answer 15

ok

Answer 16

Let us solve A

Answer 17

What does x = ?

Answer 18

-2

Answer 19

Correct, Now you must substitute (-2) for x in 12x + 4y = -12

Answer 20

Let me know what you get.

Answer 21

3

Answer 22

Nice good, i agree, does that match with our system of solutions?

Answer 23

Yes

Answer 24

So then that makes what your answer?

Answer 25

A.)

Answer 26

I agree.

Answer 27

Thanks so much

Answer 28

Answer 30

Actually just stick with A, I am not to sure on A or D

Answer 31

Unless your gut says otherwise.

Answer 32

ok

Answer 33

Sorry if you get it wrong, i just forgot how to determine if it is linear.

Answer 34

ok thanks

Answer 35

Sure thing.
