Indent all equations in a document

Question

I'm currently writing my notes on a LaTex book, and I've decided to use this template. Additionally, I'm compiling with LuaTex since I have some Feynman diagrams with tikz.

I like to write my equations on my notebook starting from 2-3 cm from the left margin, independently on how long the equation is. There is a way to have all the equations aligned that way? To have something like this

Edit: as suggested by @LuisTurcio, I've upladed amsmath and used fleqn, and it works. The problem now is that to have the equations to look like that, I need to write them inside a \begin{equation}...\end{equation}, and I mostly use $$..$$. There is a way to have this option also for those equations?

Did you have tried loading amsmath with the option fleqn? — Luis Turcio, Oct 20 '21 at 14:04
Please see the posting What are the differences between $$, \[, align, equation and displaymath? Anyway, if you want to create a displayed equation without an equation number in a LaTeX document, you should not be using the equation environment. Instead, you should be replacing $$ ... $$ with \[ ... \]. — Mico, Oct 20 '21 at 14:38
Ok I wrote only few equations so far, so not a big deal make the replacement, and now it works. There is also a way to set how much to indent the equations? Like 3 or 4 cm — john, Oct 20 '21 at 14:46

I've just combined the commands and made as suggestion...

1. $$...$$ was a PlainTeX tags, please avoid to use it.
2. if you want to create a displayed equation without an equation number in a LaTeX document, you should not be using the equation environment. Instead, you should be replacing $$ ... $$ with \[ ... \]
3. \mathindent= **cm is the tag which allowed you to indent the equations as your wish
