Question

How do you solve `4n - 12 = 12 - 4n`?

Answer 1

`n = 3`

Explanation:

`4n - 12 = 12 - 4n`

This is our given equation. Add `4n` to both sides

`8n -12 = 12`

We end up with all variable terms on one side. Now add `12` to both sides to get the variable term by itself on that side

`8n = 24`

Now all we have to do is divide out the eight from both sides to get a solution for `n`.

`n = 3`

You can check your work (as always) and plug in `3` for all variables `n`. You end up with `0=0`, which is true, which also indicates we did our work correctly and `3` is a correct solution.
