[Tex/LaTex] How to use tabs in Latex

Question

I don't want to use the \equation tag. But I want to write as follow:

Set of equations: x = y + 5
                  y = 3

I tried the alignment operator (&) but didn't work out. I tried \quad, \tab, but also couldn't get it. I tried \begin{itemize}, but it goes usually on new line, and I want the first equation on the same line.

Answer 1

Welcome! You can use the aligned environment with [t] for that.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
Set of equations: $\begin{aligned}[t]x &= y + 5\\
                  y &= 3\end{aligned}$
\end{document}
