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 + at - u#
#v - u = at#

Then, we want to divide both sides by #a# so we isolate the t:
#(v - u)/a = (cancel(a)t)/cancel(a)#
#t = (v-u)/a#
