The solution set can be given as:

Step-by-step explanation:
Given function:

To find the domain of the function in set notation.
Solution:
For the function
to exist the denominator must be ≠ 0
We have the denominator
which cannot be = 0.
Thus, we can find the domain of the function using the above relation.
The function
will not exist when:

Solving for 
Subtracting both sides by 6.


Dividing both sides by 2.

∴ 
Thus, the function will not exist at
. This means it has all real number solutions except -3.
The solution set can be given as:

There are 8 students in each class and there are 5 classes
: )
These would be 2 of the 4 equations, because 6 times 9 equals 54 and 9 times 6 equals 54, but are written in a different way. Thus meaning they are 2 of the 4 equations.
These 2 would be the final to, because 54 divided by 6 is 9, and 54 divided by 9 is 6. Thus meaning they are the final 2 equations.
