Asap! write an equation where the solution is b= -6. include like terms and fractions! in advance

First, I'd like to state there are many possibilties to for this solution.

Okay, 9/3 + 3 = -1b

Lets check.
PEMDAS!
9/3 is = 3

So:
3 + 3 = -1b

Then combine like terms:
6 = -1b

Following PEMDAS, divide -1 on both sides so..
-6 = b or b = -6

So, 9/3 + 3 = -1b works!!!
