I have some long equations. I want to achieve the followings:
- How to justify the equation to the left?
- How to align the equations as in the blue arrow?
- Just one equation number is required.
For Example;
\begin{small}
\begin{equation} \label{Eq:1}
\begin{aligned}
& f(x):\; && x^3+4 x +2\\
& g(x):\; &&x^3+3 x +4\\
&&-5 x^4+x^6\\
& h(x):\; && 0\leq x^5+6 x +7
\end{aligned}
\end{equation}
\end{small}
where \cref{Eq:1} is an example.
I read the environments alignat
, flalign*
etc. But I still can't achieve what I want.
