The equation in your post is WRONG.
Is my understanding correct that your job at this forum
is posting wittingly wrong problems, of the type 2 + 2 = 5,
and then, with blue eyes, asking/requesting, if it is correct or not, preferably with detailed explanations ?

I got this comment from you
comment from student:
1. No
2. I read the problem
3. I try setting up an equation(s)
4. I ask tutors if my set up is correct.
5. If my set up I'd correct, I can then take it from there.
Below is my response :
As I see, you like to work having a list of step-by-step instructions.
But as I look on your activity here at the forum, this list, which you
compiled for yourself in your comment, is not enough for you.
More precisely, if you are going to "solve" problems due to the intelligence and skills
of the tutors, then it is enough.
But if you want to learn solving Math problems on your own,
then you need to EXTEND your list, adding there
- read and re-read the problem until you get a complete understanding;
- Make set up checking and re-checking your job at every step,
check, then double check, then re-check, then cross check.
- At every step, apply full attention and be concentrated/focused on the problem.
It is very and absolutely normal process: these are no excessive demands here.
It is assumed (by default) that every student, wishing to learn Math,
works and does it this way with full diligence.
And take this my last instruction very seriously:
- when I recommend you my lessons to read, do not leave it without your attention.
For many people, it is necessary to see a large massive of solved problems on a subject
to get full/complete understanding the method / (methods), the terminology, and standards of presentations.
You may add this my last instruction to your list: read what is recommended to you.
