The absolute value of -3.92 is -3.92 because on a number line it the same length. Hope this helps mate
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!
