Your are on the right track.
You want to get just the variable on one side of the equation. You have done that.
Your last step above:
4 - 10 = 10n + 10 - 10
The +10 and - 10 on the right cancel
4 - 10 = 10n
Subtract 10 from 4 on the left.
Then you something on the left = 10n.
Divide both sides by 10 to find n.
