Solving $\frac{x^4}{4}+\frac{1}{y}=c$ for $y$ is giving a wrong answer I have a simple equation where I want to solve for $y$ but I am getting wrong answer using my steps with some slight sign changes. I know I am making a silly mistake somewhere but its frustrating that I can't find it. Kindly take a look.
NOTE: I know I can see steps in Symbolab but I want to know where I am wrong in my steps. Thanks
$$\cfrac{x^4}{4}+\cfrac{1}{y} = c $$
The answer should be:
$$y=-\cfrac{4}{x^4-4c}$$
but, as shown below, I am getting:
$$y = \frac{4}{4c-x^4}$$



They are equal, note that $-(x^4-4c)=4c-x^4$.
You just write in different form.
