I want to align 2 similar equations such that the first is directly over the other.

$ a + b = c $ \\
text $ d + e = f $ \\

How do I do that?

It should look like:

     $ a + b = c $ \\
text $ d + e = f $ \\

My original code:

Die Wronskimatrix entspricht dann die linear Kombination der Funktionen: \\
$ {\color{orange} \alpha x + \beta x^2 = 0}$ \\
und $ {\color{orange} \alpha 1 + \beta 2x = 0   }$ für die Ableitungen\\

I want it to look like:

Die Wronskimatrix entspricht dann die linear Kombination der Funktionen: \\
    $ {\color{orange} \alpha x + \beta x^2 = 0}$ \\
und $ {\color{orange} \alpha 1 + \beta 2x = 0   }$ für die Ableitungen\\

I tried using \begin{alinged}[b] as shown below but it didn't compile with error of missing } in a wierd place.

  • Can you provide some broader context of the information surrounding your code snippet? Specifically, this information seems to be presented in regular text/paragraph mode with line-breaks via \\. Instead, it is far better to use a display like \begin{align*}...\end{align*}.

  • Where should I place \begin{align*}...\end{align*} to avoid collisions with my code?

    With the context of your code, align* is not a viable option.

zzzzzzzzzzzz

text $\begin{aligned}[b]
   a + b &= c  \\
  d + e &= f 
\end{aligned}$

zzzzzzzzzzzzzzzzzzzzzzzzz

  • It would be nice if you showed a line of text above and another below, just to show that it works in context. (Of course, just cheating and using \phantom{text }$... would avoid all possible baseline problems.) Mar 7, 2019 at 19:07

  • The gap between the two lines with the math expressions is larger than the gap between a math line and the adjacent text line. (Not surprising, actually, since the aligned and align vertical separation is more than the default baselineskip.) Mar 7, 2019 at 20:15
  • @barbarabeeton yes, quite probably you would set the whole thing off in a display construct such as center so the \lineskip difference wouldn't be obtrusive, or you could correct fro it of course. Mar 7, 2019 at 20:53
  • Got it, I should have placed the color enviroment to encapsulate the aligned. Tnx!

\documentclass{article}
\usepackage{tabstackengine}
\TABstackMath
\begin{document}
text \alignLongstack{a + b =& c\\ d + e =& f} more text
\end{document}

enter image description here

The default baselineskip for a long stack can be set in the preamble with \setstackgap{L}{<length>}.

If it is to be literally used within typeset text, one may wish to add \strutlongstacks{T} to get proper line spacing:

\documentclass{article}
\usepackage{tabstackengine}
\usepackage[nopar]{lipsum}
\strutlongstacks{T}
\TABstackMath
\begin{document}
\lipsum[1]
text \alignLongstack{a + b =& c\\ d + e =& f}
\lipsum[2]
\end{document}

Display your formulas:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[ngerman]{babel}

\usepackage{amsmath,mathtools}
\usepackage[dvipsnames]{xcolor}

\begin{document}

\section{A}

Die Wronskimatrix entspricht dann die linear Kombination der Funktionen:
\begin{alignat*}{2}
&&& \color{orange} \alpha x + \beta x^2 = 0 \\
\text{und}&\qquad&& \color{orange} \alpha 1 + \beta 2x = 0
\end{alignat*}
für die Ableitungen.

\section{B}

Die Wronskimatrix entspricht dann die linear Kombination der Funktionen:
\begin{align*}
& \color{orange} \alpha x + \beta x^2 = 0 \\
\shortintertext{und}
& \color{orange} \alpha 1 + \beta 2x = 0
\end{align*}
für die Ableitungen.

\end{document}
