# How do you solve t-(-1)=45?

See a solution process below:

#### Explanation:

First, remember, minus a minus is a plus to rewrite the left side of the equation:

$t \textcolor{red}{-} \left(\textcolor{red}{-} 1\right) = 45$

$t + 1 = 45$

Now, subtract $\textcolor{red}{1}$ from each side of the equation to solve for $t$ while keeping the equation balanced:

$t + 1 - \textcolor{red}{1} = 45 - \textcolor{red}{1}$

$t + 0 = 44$

$t = 44$

$t = 44$

#### Explanation:

When subtracting a negative number, the number turns positive:

$t - \left(- 1\right) = 45$

$t + 1 = 45$

Now we have to variable $t$ alone. To do this, subtract $1$ from both sides

$t = 44$

Hope this helps!
