#### 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 5 to everything inside of the first set of parenthesis and the 3 to everything inside of the second set of parenthesis, giving us the equation 5t-20-3t+6=12. We now simplify:
$2t-14=12 \\\\ 2t=26 \\\\ t=13$
