Set up a function for the following situation:

The output of a function is 8 less than 3 times a number.
B) Find the input when the output is 13?
Would your equation look like: 8<3=13?
Or am I doing this wrong?
Please help!

output= 3*13-8

output=3*input - 8
output+8=3*input
Input= 1/3(output+8)

So what would the input be?
Is it 1/3?
Or are you telling me to follow those steps.. to find the input. I'm very confused.
