Answer:
-8 - 1 - 2 = -9 - 3 is not an equal expression because when both sides are simplified you get -12 from -9-3 and -11 from -8-1-2. (-11)≠(-12)
Explanation:
If you are confused with subtracting negatives from negatives there is an equal trick which can make it seem a lot more easier. Basically instead of viewing it as -9-3, you can look at it was -9+(-3). Both of these problems are the same thing, but by just adding the + in the middle makes it seem a lot more easier to interpret. Hope this helps.
