Figure out a way to isolate $t$ by subtracting and dividing

Explanation:

You goal is to isolate $t$ from the other variables.
Let's begin like we always do when dealing with equations; add or subtract.

In this case, we want to subtract $u$ from both sides.
$v - u = u + a t - u$
$v - u = a t$

Then, we want to divide both sides by $a$ so we isolate the t:
$\frac{v - u}{a} = \frac{\cancel{a} t}{\cancel{a}}$
$t = \frac{v - u}{a}$
