Answer:

Step-by-step explanation:
Division operation of function:

Example:

Start off by combining like terms on the LHS (the terms with x in them).
So we get

Replacing this result with what we had before on the LHS, we get

⇒Solve for x (divide both sides

)
⇒Don't forget about reciprocity rules when dividing. This is the same as multiplying both sides by

⇒

⇒

***This is a proper fraction
The mean is the average of a set of numbers, to find the mean, add all the numbers, then divide by the amount of numbers.
