alineación correcta en la segunda línea de una ecuación en línea

Question

Tengo una equitación en línea dentro de un entorno de artículo. El problema es alinear la segunda línea en el lado derecho. ¿Cómo lograr esto?

\documentclass[a4paper,twocolumn]{scrbook}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{enumerate}
\usepackage{amsmath}

\begin{document}

\begin{enumerate}
\item Theoretically, the calculated voltage should be
correspond to the measured voltage. But in practice it is
often \emph{not} the case. There are small deviations. Calculate first
the absolute deviations according to the rule:\\
\medskip{}\\
$\left\langle\text{absolute deviation}\right\rangle = \\ \left\langle\text{calc. value}\right\rangle - \left\langle\text{measured value}\right\rangle$\\
\medskip{}\\
The ,,measured value`` here is of course the ,,measured voltage``.\\
Calculate all absolute deviations and enter the results in the
table.
\item Further steps
\end{enumerate}

\end{document}

Answer 1

LaTeX no es un procesador de textos. El uso de \\debe limitarse a donde sea necesario terminar líneas explícitamente.

\documentclass[a4paper,twocolumn]{scrbook}

\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{lmodern}
\usepackage{enumerate}
\usepackage{amsmath}

\setlength{\multlinegap}{0pt}

\begin{document}

\begin{enumerate}
\item Theoretically, the calculated voltage should be
correspond to the measured voltage. But in practice it is
often \emph{not} the case. There are small deviations. Calculate first
the absolute deviations according to the rule:
\begin{multline*}
\langle\text{absolute deviation}\rangle = \\ 
\langle\text{calc.\ value}\rangle - \langle\text{measured value}\rangle
\end{multline*}
The ,,measured value`` here is of course the ,,measured voltage``.

Calculate all absolute deviations and enter the results in the
table.

\item Further steps

\end{enumerate}

También eliminé \lefty \righteso no hace nada útil en esa fórmula.

Nota calc.\ valuepara evitar un período de fin de oración. También podría serlo calc.\@ value.

Answer 2

El truco consiste en utilizar a \hfilldelante de la segunda línea, pero con a \mbox{}delante, porque \hfillno funciona al principio de la línea.
