Tega please spend some time with negative numbers. It would seem that instead of subtracting 12 from both sides of the equation (did you set up an equation?) you added the 12 and 36 to get 48. You then divided by 8 and got 6. If you don't respect the negative sign it will come back to haunt you almost every time.
