12a-(4b+4a)-b
12a-4b-4a-b
=> 8a-5b
21 friends.
44 - 2x = 2, where x is the number of friends Kristin has.

42 = 2x
Divide by 2 on each side.
42 / 2 = x
21 = x

Take the GCF (-8t) of the given expression.
You'll get -8t(2t-5).
Now, set each equal to zero and solve for x.
-8t = 0 2t-5=0
t=0 t = 5/2 (Or 2.5 seconds)
