## Homework Statement

Solve the following

(x+2y-1)dx +3(x+2y)dy=0

## Homework Equations

## The Attempt at a Solution

I said that it was in form M(x,y) dx + N(x,y) dy=0

then found [itex]\frac{\partial{N}}{\partial{y}}[/itex] and similarly [itex]\frac{\partial{M}}{\partial{x}}[/itex]

Meaning that it wasn't exact, but then tried to find the integrating factors, given that the equation wasn't exact. But in doing so, The formulas for the integrating factors didn't work out. Did I start this question wrong?
