Answer:
Step-by-step explanation:
y = 3*2 + 9x - 18
First step in this case is to multiply 3 * 2 = 6.
Then you would have: 6 + 9x - 18
Step-by-step explanation:
In order to get the inverse of equation, we will interchange the variables and solve for x and y as follows.

whereas, 
or x = 
Now, on interchanging the variable we will get the equation as follows.


y =
