Answer
$t=4$
Work Step by Step
$\begin{align*}
t+5&=9 &\text{Simplify the left side.}\\
t+5-5&=9-5 &\text{Subtract 5 from each side of the equation.}\\
t&=4 &\text{Simplify}.
\end{align*}$
Check if the solution is correct by substituting $4$ to the variable in the original equation:
$\begin{align*}
t-(-5)&=9\\
4-(-5)&\stackrel{?}{=}9\\
4+5&\stackrel{>}{=}0\\
9&\stackrel{\checkmark}{=}9
\end{align*}$
Thus, the solution is $t=4$.
