Well, the way you wrote it, you would have:(4x - 5y - 3) x 3x + 5ywhich would give12x^2 - 15xy - 9x + 5yBut, if you meant the quantity (3x + 5y), then you would have:(4x - 5y - 3) x (3x + 5y)which would give12x^2 - 15xy - 9x + 20xy - 25y^2 - 15yand combining terms12x^2 - 25y^2 + 5xy - 9x - 15y

The Abelian property or commutativity.
- X + 5Y - 4X + 7 gather terms - X - 4X ( same as - X + (- 4X ) 5Y 7 = - 5X + 5Y + 7 ----------------
3x+5y+8x+2y combine 3x and 8x to get 11x 11x+5y+2y combine 5y and 2y 11x+7y is the answer.
X = -2(13 + y) / 3x = 5y / 4 - 1

no, 4x-3y=11x 3x-5y doesn't equal -11
