See a solution process below:

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

$t - (- 1) = 45$ $t color(red)(-) (color(red)(-)1) = 45$

$t + 1 = 45$ $t + 1 = 45$

Now, subtract $1$ $color(red)(1)$ from each side of the equation to solve for $t$ $t$ while keeping the equation balanced:

$t + 1 - 1 = 45 - 1$ $t + 1 - color(red)(1) = 45 - color(red)(1)$

$t + 0 = 44$ $t + 0 = 44$

$t = 44$ $t = 44$

$t = 44$ $t=44$

When subtracting a negative number, the number turns positive:

$t - (- 1) = 45$ $t-(-1)=45$

$t + 1 = 45$ $t+1=45$

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

$t = 44$ $t=44$

Hope this helps!
