$a = (2(s-ut))/(t^2)$

$s = ut + 1/2at^2$

subtract $ut$ to isolate the term containing $a:$

$s - ut = 1/2at^2$

multiply by $2:$

$2(s-ut) = at^2$

divide by $t^2$ to isolate $a:$

$(2(s-ut))/(t^2) = a$

with $a$ on the left-hand side,

$a = (2(s-ut))/(t^2)$

or, alternatively (if expanding brackets)

$a = (2s-2ut)/(t^2)$
