Answer

$t=-3$

Work Step by Step

The distributive property allows us to distribute anything multiplied by something inside of the parenthesis to whatever is inside of the parenthesis. Thus, we distribute the -4 to everything inside the parenthesis, giving us the equation -4t-28=-16. We now simplify: $-4t=12 \\\\ t=-3$
