Multiply the equation:
The solution set is the same, because multiplying both sides of an equation by a non-zero number doesn't change the solution set. In fact, if you rewrite the equation as
Multiplying this by 3 (or whatever number, for all it matters) gives
Now, a product is zero if and only if at least one of the factor is zero. So, either 
or
Since the first is clearly impossible, the second one must be true, which is the original equation.

y + 9 = 9
Subtract 9 to both sides to isolate the 9 on the y. Whatever you do on one side you have to do it to the other side, your answer should be
y + 9 = 9
- 9 - 9
y = 0
Answer:
11
Step-by-step explanation:
Use the same denominator then divide.
This is a cubic binomial.
