Answer :

TSO
S -1/2 = 1/2

Add 1/2 to both sides so

S - 1/2 + 1/2 = 1/2 + 1/2

Simplify it:

S = 1

So S = 1
Lets solve this step by step! :)
s - 1/2 = 1/2

Step 1: Simplify both sides of the equation.

s + -1/2 = 1/2

Step 2: Add 1/2 to both sides.

s + -1/2 + 1/2 = 1/2 + 1/2

Here is you're answer! s=1 or just 1

I hope this helps! :D
