<em>ANSWER:</em>

<h2>7k</h2>

<em>STEP:</em>

Add -k and 8k. If you don't know why, since there is two "-". Two of those sign mean to add. And negative plus a positive is negative or positive. Or, you can just do 8k-1k. That is the same. You'll get 7k.

-k-(-8k)

= -k + 8k (two negatives equal one positive)

= 8k-k (flip it around because of the commutative property)

=7k (basic subtraction)

I really hope that helped :)
