The output with the code is all wrong. How can I get it to start "X" centimeters from the left margin?

The third term can be expanded as follows:
\begin{subequations}
\begin{align}
-E[2P_hL_hQ(P_h-\bar{P})]\\
&=-2QE[(P_h-\bar{P}+\bar{P})(L_h-\bar{L}+\bar{L})(P_h-\bar{P})]\\
&=-2QE(P_h-\bar{P})^2(L_h-\bar{L})\nonumber\\
&\qquad -2QE(P_h-\bar{P})^2\bar{L}\nonumber\\
&\qquad -2QE\bar{P}(P_h-\bar{P})(L_h-\bar{L})\nonumber\\
&\qquad -2QE\bar{P}\bar{L}(P_h-\bar{P})\nonumber\\
\text{after tedius manipulation, can be reduced to}\\
&=-2QE(P_h-\bar{P})^2(L_h-\bar{L})\nonumber\\
&\qquad -2Q\bar{L}\sigma_{P_hL_h}
\end{align}
\end{subequations}
\end{document}
Thanks!!
