Equation and italics

Question

How do I write the equation

{x|A'x=b'}

in LaTeX and make it italic? I have tried following code:

 \textit{{$$x|$$A'x=b$'}}

but it did not work. The dollar signs are in wrong places.

I recommend looking at a getting started guide to LaTeX. I don't know where to begin explaining, but the correct code is \[ \{x \mid A'x=b'\} \] or similar. — Will Robertson, Mar 07 '16 at 13:06
For more information on why one shouldn't use $$ in LaTeX documents, see the postings Why is \[ … \] preferable to $$ … $$? and What are the differences between $$, \[, align, equation and displaymath? — Mico, Mar 07 '16 at 14:26

Don't try to manually create a math environment, by using \textit. For inline math use $ and use $$ or an environment for interline math. $\{x'\mid A'x=b'\}$

The curly braces have to be set by \{, since a single brace is a grouping token in LaTeX, so it will be ignored in the output.

Please don't suggest to use $$ in conjunction with LaTeX. \[...\] is the correct form for LaTeX, not $$...$$ – Mar 07 '16 at 13:54
