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

12x + 4y = -12
15x = -30

8x + 4y = -4
14x = -10

6x - 8y = -36
-6y = -42

6x - y = -15
3y = 9

Answer 7

Do you mean which of the last 4 systems has the same solution as the first system?

Answer 8

nno

Answer 9

Then what is "the one given below"?

Answer 10

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

Answer 11

So you want to know which of the other systems has the same solution as that one?

Answer 12

I'd say you need to get to solving the systems so you can find out

Answer 13

@Mertsj help

Answer 14

@ehuman do you know the answer

Answer 15

Solve the first system like this:

Answer 16

1. Multiply first equation by 2
2. Add that answer to the second equation
3. Solve the result for x
4. Plug x into the first equation and find y

Answer 17

idk how to do that

Answer 18

What is the first equation?
