Solve for b.

-1/3b=9

What is the answer?

-1/3b = 9

b = 9 * - 3

b = - 27

-1/3b=9

Divide - 1/3 on both sides

b = 9 divided by - 1/3

Convert the 9 into an improper fraction

b = 9/1 divided by - 1/3

Convert the division sign to multiplication while flipping the fraction - 1/3 to - 3/1

b = 9/1*-3/1

Multiply

Final Answer: b = - 27
