Hey!
------------------------------------------------
Steps To Solve:
9b = -6 + 10b
~Subtract 10b to both sides
9b - 10b = -6 + 10b - 10b
~Simplify
-1b = -6
~Divide -1 to both sides
-1b/-1 = -6/-1
~Simplify
b = 6
------------------------------------------------
Hence, the answer is [tex]\Large\boxed{\mathsf{b~=~6}}[/tex]

Hope This Helped! Good Luck!
