Answer:
Answer is below
Step-by-step explanation:
Add 9 to both sides.
![6b-9+9=-87+9\\6b=-78](https://tex.z-dn.net/?f=6b-9%2B9%3D-87%2B9%5C%5C6b%3D-78)
Divide both sides by 6
![\frac{6b}{6} =\frac{-78}{6} \\b=-13](https://tex.z-dn.net/?f=%5Cfrac%7B6b%7D%7B6%7D%20%3D%5Cfrac%7B-78%7D%7B6%7D%20%5C%5Cb%3D-13)
Answer:
D.
(The only option that makes sense is D. but I came up with 10°F when I did the math)
