3x-3y
Collect like terms: 3x - x + 4x - 4y + 6y + 2 = 6x + 2y + 2
To simplify the expression (9x + 4y - 6x - 5y), combine like terms. For the (x) terms, (9x - 6x = 3x), and for the (y) terms, (4y - 5y = -1y) or (-y). Therefore, the simplified expression is (3x - y).
It is: 2-3x simplified
-3x+9x can be simplified to 6x
It is an expression that can be simplified to 4x
(6x - 5y) + (-3x - 4y) =6x - 5y - 3x - 4y =3x - 9y =3 (x - 3y)
Collect like terms: 3x - x + 4x - 4y + 6y + 2 = 6x + 2y + 2

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.
It is: 3x-2 simplified
3x + 6x = 9x
It is an expression that can be simplified to 4x
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 --------------------
There can be no answer because there is no equation. There is an expression that can be simplified but that is not an answer.
