Lets go step by step and factor out each as we go
first lets factor out a 3 since 3 is common in 9 and 3
3(3ab^2 - abc)
now lets factor out a since its common in both
3a(3b^2 - bc)
now lets factor out a b since its common in both
3ab(b - c)
we can't factor anything else out so we are done.

Answer:
x = 9/4
Step-by-step explanation:
Solve for x. Start by adding 6x to both sides, which results in 3 + 4x = 12.
Combine the constants, obtaining 4x = 9.
Dividing both sides by 4, we get x = 9/4.
