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!
