Need help on log question urgent, mock exam tomorrow

I know it seems like a basic Cartesian equation question, but for some reason I'm struggling to rearrange equation x to find an equation for t to substitute into equation y. Can somebody help with this question?

COMPLETE THE SQUARE OF t^2 + 6t -16
