-3x+9x can be simplified to 6x

It is: 2-3x simplified

It is: 3x-2 simplified

We can certainly simplify that term. 6x - 3x = 3x. And -4y + y = -3y. So the simplified expression is 3x-3y. You could also call this 3(x-y). That's as far as we can go, since we have no way to evaluate x or y without further information.

3x + 6x = 9x

We will see. 3X + 2Y = 15 6X + 4Y = 30 I do not like the look of elimination, so substitution 3X + 2Y = 15 3X = 15 - 2Y X = 5 - 2/3Y -------------- 6(5 - 2/3Y) + 4Y = 30 30 - 12/3Y = 30 30 - 4Y = 30 this is inconsistent in approach 3(5 - 2/3Y) + 2Y = 15 15 - 15/3Y = 15 another bad approach, try elimination to show inconsistency - 2(3X + 2Y = 15) 6X + 4Y + 30 -6X - 4Y = - 30 6X + 4Y = 30 I think it is safe to say these systems of equations are inconsistent --------------------
