To solve the equation \( s + (-3) = -5 \), we need to isolate the variable \( s \). We can do this by adding 3 to both sides of the equation.
Step 1: Isolate the Variable
To solve the equation \( s + (-3) = -5 \), we need to isolate the variable \( s \). We can do this by adding 3 to both sides of the equation:
\[
s + (-3) + 3 = -5 + 3
\]
