$d = v_{0^{t}} + \frac{a t^{2}}{2}$

Step 1

Rewrite the equation as $v_{0^{t}} + \frac{a t^{2}}{2} = d$ .

$v_{0^{t}} + \frac{a t^{2}}{2} = d$

Step 2

Subtract $v_{0^{t}}$ from both sides of the equation.

$\frac{a t^{2}}{2} = d - v_{0^{t}}$

Step 3

Multiply both sides of the equation by $2$ .

$2 \frac{a t^{2}}{2} = 2 (d - v_{0^{t}})$

Step 4

Simplify both sides of the equation.
