I have another problem!

I always get a bit confused if there's a minus sign in front of a number.
The book says the answer is 2/3
So what I first did was.
which is 1 1/2, and wrong.?

  • Math -

    divide both sides by 6

  • Math -


    4 - 2y + 2y = 4y + 2y
    4 = 6y

    Here you need to divide by sides of the equation by 6.

    4/6 = y
