$12w - 28$

$8w - 4(7-w)$

First, use the distributive property to simplify $color(blue)(-4(7-w))$ :

Based on this image, we know that:
$color(blue)(-4(7-w) = -28 + 4w)$

Let's put that back into the expression:
$8w - 28 + 4w$

Let's highlight the like terms:
$color(red)(8w) - 28 quadcolor(red)(+quad4w)$

Combine the like terms:
$12w - 28$

Hope this helps!
