Hello, your writing was absolute nonsense (sorry).
As I understand, it should be
- + - .
Did I decipher correctly?
If so, then the solution is as follows:
- + - =
- + - =
- =
- =
. - =
= * - = - = .
Do you understand every step of these transformations?
If not, let me know and send you comment/question in the section "Comment from student".
If you want to learn how to write these formulas in the site's internal editor, find the button "Source code" and click in it.
I saw that you just made first steps, so you can go further and improve your skills.
