HMT cheating on homework
 

Math is not my strong point. It's probably my weakest subject. So, I need someone to help my stupid ass with this ----.

The problem is (x^3)y -2y = 6 . I need to show if the equation defines y as a function of x. I already know that it does thanks to the answer key, but I need to show how.

I've gotten as far as -2 = x^3 - (6/y), but I don't remember how to make y by itself. Can anyone help me along?

First group the left side of the equation because each term has a y

y(x^3-2)=6

divide both sides by y

x^3-2=6/y

add 2 to both sides

x^3=(6/y)+2

take cubed root of both sides

x=cube root[(6/y)+2]
