I already typed a long drawn out post, so I am going to simplfy it. I am having trouble using algebra to rearrange equation. For Example, v=d/t And so, to solve for both t and d, I do the following vt=d/t x t vt=d vt/v=d/v t=d/v I have difficulty with most if not all the other equations. For example, the formula for acceleration. a=Vf-Vi/t Solve for t a=Vf-Vi/t at=Vf-Vi/t x t at + Vi=Vf -Vi + Vi at+Vi=Vf Vf-Vi/a=t This is my attempt at it. I multiplied by t, then eliminated the negative, and finally divided by a. Thank you ahead of time!
