how to write more words on the same line

Is there any way to write the number 37 from the below image on the same line with equal sign?

\textbf{3.} Afla\c ti de\^ imp\u ar\c titul \c stiind c\u a \^ intre \^ imp\u ar\c titor, c\^ at \c si rest avem rela\c tia $i^2+c^2+r^2=37$.


Thanks!

• could you give us some starting code, preferably an MWE – Runar Aug 11 '16 at 18:59
• You could reduce the textsize, or put it inside a \makebox[\linewidth][l]{text} – Runar Aug 11 '16 at 19:13
• Can you show us a little more context? With 3. it seems like you're manually enumerating content. Is this the case? Does the line start at the left margin, or indented? – Werner Aug 11 '16 at 19:14
• The simplest solution is to use \mbox{$...$} to make the inline math unbreakable. The results my be a bit ugly, with either a large gap or extending into the margin. – John Kormylo Aug 11 '16 at 22:07
• Short answer: no. If TeX breaks the line at the equals sign, it's almost sure that the number and the period cannot fit. – egreg Aug 12 '16 at 13:35

Rather than enclosing the math formula inside \mbox, as John Kormylo suggests, I’d define a command that prohibits line breaks inside a math formula. Indeed, this allows the glue inside the formula to stretch and shrink together with other glue on the same line, whereas John’s solution does not.

% My standard header for TeX.SX answers:
\documentclass[a4paper]{article} % To avoid confusion, let us explicitly
% declare the paper format.

\usepackage[T1]{fontenc}         % Not always necessary, but recommended.
% End of standard header.  What follows pertains to the problem at hand.

\makeatletter

\newcommand*{\prohibitmathbreaks}{%
\binoppenalty \@M
\relpenalty \@M
}

\hyphenpenalty = \@M % ONLY for this example: DO NOT INCLUDE IN YOUR DOCUMENTS!

\makeatother

\begin{document}

Some meaningless text, inserted just to get near\ldots\ the end of the line.
$$x+y=a+b\prohibitmathbreaks$$.
And some more random text that adds other lines, which~contain~an unbreakable
sequence of words, to show that the spaces inside the formula \emph{are} allowed
to shrink.

On the other hand, if one uses the \verb|\mbox| solution, this does not happen:
\mbox{$$x+y=a+b$$.}
And: some more random text that adds other lines, which~contain
unbreakable~sequences~of~words.

Another paragraph, containing another formula, in order to show that the effect
of our \verb|\prohibitmathbreaks| command is kept local:
$$a+b+c+d+e = x+y+z$$.

\end{document}
