That would be the inverse property of addition. When you add the opposite of a number to that number, your sum will be zero. -a is the opposite of a and -bi is the opposite of bi. When you add x + y (aka the opposites) your total is absolutely nothing!

It’s A
Because if you subtract 12 from 96 you’ll get 8y=84 then divide both sides by 8 you get 21/2 simplify and get 10.5 or 10 1/2
