I am using the following environment to align optimization problem statements from Typesetting an optimisation problem
\documentclass{report}
\usepackage{amsmath}
\newcommand{\norm}[1]{\lVert#1\rVert_2}
\begin{document}
\begin{subequations}
\begin{alignat}{2}
&\!\min_{x} &\qquad& \norm{f(x)}^2\label{eq:optProb}\\
&\text{subject to} & & \alpha + (\beta*\gamma)\geq 0,\label{eq:constraint1}\\
& & & \beta \geq 0.\label{eq:constraint2}
\end{alignat}
\end{subequations}
\end{document}
How can I additionally align the "condition" at the \geq
sign such that it looks like this:
