A number, n, is multiplied by 6....
We get: 6n

...The product is increased by 24
We get: 6n + 24

...Finally, the entire quantity is divided by 3.
We get: (6n + 24)/3

Check answer choices....not there. We need to simplify.

Use the rule that says: (a + b)/c = a/c + b/c

So, (6n + 24)/3 = 6n/3 + 24/3
= 2n + 8
