To evaluate x - y for x = - 13 an y = - 15 replace x with -13. an y with -15 an evaluate

Answer 1

So you simply plug in the numbers for the variables. -13+15. The reason why it's 15, because the y was already negative so 2 negatives make a positive.

Now, just add -13+15 which is 2. I hoped this helped!
