# Find the iterated integral

## Homework Statement

Find the iterated integral:

$$\int\int(2x+y)^{-2}$$dydx

The first integral is from 3 to 4 and the second is from 2 to 3.

## The Attempt at a Solution

My first thought would be to do u-substitution, but wouldn't that cause problems when trying to differentiate (2x+y) with respect to y?
