Answer 2

Choose the equivalent system of linear equations that will produce the same solution as the one given below.

6x + 2y = -6
3x - 4y = -18


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 3

I think that it is either a or c...

Answer 4

have you tried solving the system of equations given to find x and y, then plugging in x and y into the choices?

Answer 5

hint: they are using elimination to get the second equation in the answers. why don't you give it a shot with the original eqns...

Answer 6

the person isn't even here!

Answer 7

:/

Answer 8

I'm right here. It's just that OpenStudy is not working and is not giving notifications.

Answer 9

I can't find x and y @DemolisionWolf T.T

Answer 10

did you eliminate?

Answer 11

If your not sure how to find x and y using substitution, then you will want to use elimination to solve this problem like pgpilot326 says

Answer 12

Well, I got the answer - it was a.

Answer 13

thnaks.

Answer 14

ur welcome
