Final Answer:
n = (6y + 9) / 3x
Step-by-step explanation:
Isolate n: To solve for n, we need to move all other terms to the other side of the equation.
Add 9 to both sides: 3xn = 6y + 9
Divide both sides by 3x: n = (6y + 9) / 3x
Therefore, the solution for n is (6y + 9) / 3x. Note that this is the simplest form of the solution, and it may not be possible to further simplify it without additional information about the values of y and x.
