Here is my shortcut for completing level 5 of can you escape horror.
Take the hammer and break the crack in the wall to get the bottle. Now fill the bottle with water from the cupid statue. Tap the sofa and use the bottle to move the doll in order to take the shovel.
Use the shovel to dig the cracked floor. Open the coffin to get the paper. Tap the chair and cloth to get the brown object. The solution to the math problem is 3705. Tap the table, use the lighter to light the candle and enter 3705 to open the locker in order to get the keys to the door.
