Make magic from Mathematic! It's fun

Think 1 number. Up to you.
Plus by 5
Minus by 10
Times by 2
Times by 3
Divided by 6
Plus 10
Minus by number that you think..
Result : It's 5... Isn't it??

Why it can be?
Here is the formula :

X + 5 - 10 x 2 x 3 / 6 + 10 - X = +5

or the logical think is:

X + 5 x 2 / 2 - X = +5
