-7+s = 29
s = 29+7
= 36
Change the sign behind the number because you are moving the number 7 from the left to the right.
E.g. the '=' is the magic bridge. Whenever the numbers or alphabets move from one side to another, the magic bridge will change the sign.
The story should help you to remember it.
Hope I've helped you! :)
