make the letter in the bracket the subject of the following formula
v = u + 5t (t)
v = u + 5t
u + 5t = v
5t = v-u
one more step
t = (v-u)/5 , these brackets are needed, or, if you don't like them
t = v/5 - u/5
v = u + 5t (t)
u + 5t = v
5t = v-u
one more step
t = (v-u)/5 , these brackets are needed, or, if you don't like them
t = v/5 - u/5
