Okay for elimination, I'm having trouble with doing it for things that have negative numbers at the end. So like, a problem with 2x + 3y = -12 { } -4x -3y = -16 Probably need a better example but I need help putting this all together for complicated ones and such. I understand that I need to add (-16) or -12, but if it were -16 I know I would add (-4x -3y) since -4x-3y=-16 to 2x+3y=-12 but I just get lost in translation with the negatives for the variables, not so much with this problem but with other ones.

Well, you just have to remember that your goal is to eliminate one of the variables. If you focus on that you will know whether you should be adding or subtracting the equations.
You should be able to handle -12 and -16 whether you are adding or subtracting.

Perhaps you can give me another example?
