Question

I'm kind of confused on what I got wrong on this math question....can someone plz explain

Answer 1

see the attached picture, the answer is A

Answer 2

(2x - 8) - (4x + 8)

first look at the x

2x - 4x = -2x

-2x is left over

then look at the numbers


8 - (-8)

in the case of having two negatives, it becomes positive, and so it is really 8 + 8

8 + 8 = 16


-2x - 16 is your answer

hope this helps
