basic equation trouble

My trouble is I can't remember the order to alter equations. If a=(Vf-Vi)/t how do I get it to be Vf instead of a? Other, more complicated examples like d=((Vxf -Vxi)/t) + (1/2)a(t^2) changed to = 'Vxf=equation' would be more beneficial for me, but the basic order of things works just as well...this is a refresher and I can't recall the term for this action, so I haven't been able to find any resources on it.

Thanks!

You may find the topic"change of subject"
a=(Vf-Vi)/t
Multiply t on both sides
at=(Vf-Vi)
Add Vi on both sides
Vf=at+Vi

For more complicated examples, simply put things other than the term you want to other side.
