Answer 1

$-100=12t-4\\\\12t-4=-100\ \ \ \ |both\ sides\ +4\\\\12t=-96\ \ \ \ |both\ sides\ :12\\\\\underline{\underline{t=-8}}$

Answer 2

The answer to your question is:  Yes, I can.

=================================

Although you didn't ask for the solution, I'm here now, so
I might as well follow through and make good my boast.

-100 = 12t - 4

Add 4 to each side of the equation:

-96 = 12t

Divide each side by 12 :

-8 = t
