Not such good Algebra.
0.5 is a factor. It's not added or subtracted.

$s=-\frac12 at^2$

Multiply both sides by $\displaystyle \ -\frac2a\$

You probably should take a few minutes to review basic algebra before going any further with physics.

lol, thanks guys. It's been years since I've done this kind of stuff! I've totally forgotten what to do when there's a negative number involved.

Appreciate the help @SammyS and @SteamKing

You're welcome.

It's more a matter that the numbers are all multiplied, rather than that there is a negative.
