$-2r + 8s + 12t$

To solve this you multiply each term within the parenthesis by $color(red)(-2)$ You need to ensure you handle the sign of each term correctly:

$(color(red)(-2) xx r) + (color(red)(-2) xx -4s) + (color(red)(-2) xx - 6t)$

$(-2r) + (+8s) + (+12t)$

$-2r + 8s + 12t$

How do you simplify -2(r-4s-6t)-2(r-4s-6t)?
