Sorry!
I have another problem!

4-2y=4y
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.
4-2y=4y
4=6y
which is 1 1/2, and wrong.?

  • Math -

    4=6y
    divide both sides by 6
    2/3=y

  • Math -

    4-2y=4y

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

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

    4/6 = y
