oops...
I have made an error, sorry. The rigt steps, are:
\[\large y + 5 = 3{x^3}\]
so:
\[\large x = ...?\]

Answer 7

\[x = \sqrt[3]{y+5}\div \sqrt[3]{3}\]

ok! Now we have to replace x with y and y with x, what do you get?

Answer 9

So basically \[\left(\begin{matrix}x+5 \\3\end{matrix}\right)^1/3\]
