alinhamento à direita na segunda linha de uma equação embutida

Question

Eu tenho uma equitação embutida dentro de um ambiente de item. O problema é alinhar a segunda linha do lado direito. Como conseguir isso?

\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 não é um processador de texto. O uso de \\deve ser limitado onde for necessário terminar explicitamente as linhas.

\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}

Eu também removi \lefte \rightisso não faz nada de útil nessa fórmula.

Nota calc.\ valuepara evitar um período de final de frase. Também poderia ser calc.\@ value.

Answer 2

O truque é usar um \hfillna frente da segunda linha, mas com um \mbox{}na frente dela, porque \hfillnão funciona logo no início da linha.
