Which of the following equations have the same solution as the equation 3x+2y=-12 ? check all that apply. 3x-2y=12 -3x-2y=12 15x+10y=-60 6x+2y=-12 6x+4y=-24 1.5x+y=-6 x+ 2/3y=-12

If one equation is the same, there is a multiply factor:

f*(3x+2y)=f*(-12)

You need to find the same factor for both members.

3x-2y=12. This is not the same.

-3x-2y=12. This is the same. The factor is (-1)

15x+10y=-60. This is the same. The factor is 5.

6x+2y=-12. This is not the same.

6x+4y=-24. This is not the same.

1.5x+y=-6. This is the same. The factor is 1/2.

x+ 2/3y=-12. This is not the same.

Good luck!
