**MathMate**, Sunday, October 4, 2009 at 3:48pmWe try to isolate the target variable a on the left hand side of the equation.

h=at-(1/4)vt²

h-at = at-at -(1/4)vt² (subtract at on each side)

h-at = -(1/4)vt²

h-h -at = -(1/4)vt² -h (subtract h on each side)

-at = -(1/4)vt²-h

Now divide by -t on each side

-at/(-t) = (-(1/4)vt²-h)/(-t)

a = ((1/4)vt²+h)/t

=(1/4)vt + h/t
