The image contains a first-order differential equation that needs to be solved using an appropriate method. The equation given is:

\[
\frac{dy}{dx} = \frac{x + 2y - 3}{2x - y - 3}
\]

To solve this differential equation, we will use the method of **homogeneous equations**. 

### Step-by-Step Solution:

1. **Check if the differential equation is homogeneous:**

   Rewrite the equation as:
   \[
   \frac{dy}{dx} = \frac{x + 2y - 3}{2x - y - 3}
   \]

   Let's transform the equation by a substitution. Define:
   \[
   y = vx \implies \frac{dy}{dx} = v + x \frac{dv}{dx}
   \]

   Substituting into the equation gives:
   \[
   v + x \frac{dv}{dx} = \frac{x + 2(vx) - 3}{2x - (vx) - 3}
   \]
   Simplify the right side:
   \[
   v + x \frac{dv}{dx} = \frac{x(1 + 2v) - 3}{x(2 - v) - 3}
   \]

2. **Solve for the integrating factor (if applicable), and proceed to separate variables to integrate.**
