## Homework Statement

The problem, more like a riddle, that our teacher gave it to us was to find the error in this particular equation:

integral of 1/x dc = ln (absolute value of (x)) + C ; perfectly fine

integral of dx/3x = 1/3 integral of dx/x ; also fine

1/3 integral dx/x = 1/3 ln (absolute value of x) + C ; not sure from here

integral of dx/3x ≠ 1/3 ln (absolute value of 3x) + C

## The Attempt at a Solution

I have trying to figure out from step by step, however, I do not find what is wrong or what the error is. Could someone help with this problem? Thanks!
