Answer
$s=3$
Work Step by Step
$\begin{align*}
s-2+2&=1+2 &\text{Add 2 to each side of the equation.}\\
s&=3 &\text{Simplify}.
\end{align*}$
Check if the solution is correct by substituting $3$ to the variable in the original equation:
$\begin{align*}
s-2&=1\\
3-2&\stackrel{?}{=}1\\
1&\stackrel{\checkmark}{=}1
\end{align*}$
Thus, the solution is $s=3$.
