Answer 2

so it is d

Answer 3

It's not D. Add 9 to both sides. What do you think the answer is now?

Answer 4

c..?

Answer 5

(-5) - 9 = (-5) + (-9) = (-14). So it would not be D

Answer 6

(-36) - 9 = (-36) + (-9) = (-45) So it would not be C

Answer 7

b

Answer 8

Think about this. A = 5. Solve for x. 5 - 9 = ?

Answer 9

im so confused!!

Answer 10

so it has to be a

Answer 11

Solve for x. Try all of the answers in place for x and see which one comes out to the answer (-4).
ex.
a.5 - 9 =?
b.(-13) - 9 = (-13) + (-9) =?
c.(-36) - 9 = (-36) + (-9) =
d.(-5) - 9 = (-5) + (-9) =

^ That is all the problems you have to work out. i have labeled which answer is in place of x. Solve those problems, and see which one leads to (-4)
