Unfortunately there is a typo. There should only be one copy of an equal sign.
Please revise and repost. Thank you.

"what is the answer" is not an appropriate question in Math problems.

The answer depends on "what is the question".

Probably the student forgot to press the shift key, and one of
the equal signs should have been a " + ", which is what you get when
you hold the shift key down while pressing the " = " key.

Maybe they meant this: 

x + 4x - 3 = 12
    5x - 3 = 12
Add 3 to both sides:
        5x = 15
Divide both sides by 5
         x = 3         

Or maybe this:

  x = 4x - 3 + 12
  x = 4x + 9
Subtract 4x from both sides
-3x = 9
Divide both sides by -3
  x = -3
