-3(b + 9) = -9
First, divide both sides by -3. / Your problem should look like: b + 9 =
Second, simplify
to 
/ Your problem should look like: b + 9 =
Third, simplify to 3. / Your problem should look like: b + 9 = 3
Fourth, subtract 9 from both sides. / Your problem should look like: b = 3 - 9
Fifth, simplify 3 - 9 to get -6. / Your problem should look like: b = -6
Answer: b = -6
