How to set X in mathematical equations is generally just a general rule.

You can set anything you want directly, but sometimes direct setting will lead to complicated listed relationships and difficult equation solving;

Sometimes it is necessary to indirectly set the unknown. The key is to find the relationship between different quantities and list simple equations.

For example, there are five numbers with equal errors and a tolerance of 5, and their sum is 200. Find these five numbers.

If the first number is set to x, the other four numbers are X+5, X+ 10, X+ 15 and X+20.

Then add them up to 200, and you can find X.

But if the middle is X, the number of 5 is X- 10, X-5, X+5, X+ 10.

It's very simple to add them up and get 5x = 200 and x = 40 directly. Other numbers will be obtained soon.
