    Divide both sides by 3x+6y

    Since w is only on the right side multiplied by a factor, divide both sides by that factor

    Now try to factor the numerator on the left. First divide it by three. The factor you divided by 3x + 6y can also be factored. A 3 comes out.

    Are you sure last term on original problem's left side is 6x^2 and not 6y^2?

    You have 6x^2. I asked you if it's 6y^2, and you say you're sure it's 6y. Which is it: 6x^2 6y^2 6y
