How do you subtract 3k from -2k?

1 Answer



When you get this set up, you will first use the "keep, change, switch" method, which means you will keep the first number/variable the same, change the sign in between, and then switch the sign of the last number/variable. You then get 3k+2k because you change the minus to a plus and the negative to the positive. So your answer would be 5k. Hope this helped!
