$-7n + 32$

$-7(n-5)-3$

First, use the distributive property as shown here to expand $-7(n-5)$ :

Following this image, we know that:
$color(blue)(-7(n-5) = (-7 * n) + (-7 * -5) = -7n + 35)$

Now put that back into the complete expression:
$-7n + 35 - 3$

Simplify $color(blue)(35-3)$ :
$-7n + 32$

Hope this helps!
