It would be 8. To solve, look at it like this: 8-b=(-2). I would then look at a number line or create one if your not to sure of yourself. 8-8=0, and then 0-2=-2. 2+8=10 (the numbers you subtracted). So the answer is 10.

A. Sam withdrew $10 from his account between Monday and Tuesday.

Imagine a number line 8 is 8 spots away from 0 and -2 is 2 spots away from 0.

And if you add 8+2=10 it doesn't matter in this equation that the number is a negative because you want to find out how much money he took out.

Which would lead for you to see that on a number line that 8 and -2 are 10 spots away from each other.

In this unit, my teacher has taught me to always to refer to a number line.
