Answer:
7p+7q+63
Step by step:
Distribute 7 to p, q and 9
For this case we must find the inverse of the following function:

For this, we follow the steps below:
We change f (x) to y:

We exchange the variables:

We solve for y:

We divide between 8 on both sides of the equation:

We raise both sides of the equation to the square to remove the root:

So, the inverse is:
