LaTeX issue

Can anyone help me regarding writing in latex. I have a bit problem in aligns and gaps between words.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.

What particular line/align/gaps are you stuck on?

How can I write a statement and after a gap write it's proof in bracket. Can you tell how to align all my solution. Like- $2x = 4y \\ x = 2y ({\text{dividing both sides by 2}}$ . How can I leave gap between the equation and reason as on line 2. And also how can I align this statement or write this statement in a clean and straight line.

Beginner's version:

$2x =4y \\ x = 2y$

Intermediate version:

$\begin{aligned} 2x &=& 4y \\ x &=& 2y \end{aligned}$

Hard version:

$\begin{aligned} 2x &=& 4y \quad \text{(divide both sides by 2)} \\ x &=& 2y \end{aligned}$

Isn't there any thing like left, right or centre align. Thanks for the reply. Can you tell me, how can i learn LaTeX perfectly.

@Nikhil Raj – Use " \begin{array} " and " \end{array} " instead.

Use SearchOnMath to get better at $\LaTeX$ .
