I need help soling for the variables listed

1) a= (v-v_0)/t Solve for v_0
2) v ̅= (x-x_0)/t Solve for t
3) x=1/2 at^2 Solve for t
4) x=x_0+v_0 t+1/2 at^2 Solve for t
the _ are subscripts and ^ exponents

1) a= (v-v_0)/t Solve for v_0

V-at= Vº

2) v ̅= (x-x_0)/t Solve for t
t=(X-X°)/V

3) x=1/2 at^2 Solve for t
±√(2x)/a=t

4 is quadratic equation, use quadratic formula
