    You are going to have to be more specific. What kind of problem(s) are you thinking about?

    Post E.G. S=Vot + 1/2gt^2 = Vo=S - 1/2gt^2 / T

    Problem no.1: from the equation, A=at+v, determine the formula for a

    Problem no.2: S=Vo t+ 1/2 at^, for Vo,a

    PROblem no.3: v= Vot + at^2, for Vo,a

    You solve these the same way you would solve them if the A, t, and v are just numbers (which in reality they are.)

    Step by step:
    A = at + v

    A - v = at + v - v

    A - v = at

    \frac{A - v}{t} = \frac{at}{t}

    a = \frac{A - v}{t}

    For V_0:
    S = V_0t + \frac{1}{2}at^2

    S - \frac{1}{2}at^2 = V_0t + \frac{1}{2}at^2 - \frac{1}{2}at^2

    V_0t = S - \frac{1}{2}at^2

    \frac{V_0t}{t} = \frac{S - \frac{1}{2}at^2}{t}

    V_0 = \frac{S}{t} - \frac{1}{2}at

    You solve for a.
