Answer 2

-4

Explanation:

Using a number line can help solve this problem

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1

To add a positive number to a negative one, we are going to move that number of spaces to the right (We are adding positive 3 to negative 7, so we are moving 3 spaces to the right)

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1

^ We start here at negative 7

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1

^ ^ ^ Then move three to the right

-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 1

So -4 is our answer
