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

Sorry for coming In late! For the first question - The correct choice would be the last one ---> http://www.wolframalpha.com/input/?i=-2x+%2B+y+%3D+1+and+-4x+%2B+y+%3D+-1 <---- The second one Is rather confusing though >.>
