**

We can identify that the differential equation has the form: $\frac{dy}{dx} + P(x)\cdot y(x) = Q(x)$, so we can classify it as a linear first order differential equation, where $P(x)=\frac{3}{x}$ and $Q(x)=\frac{1}{x^2}$. In order to solve the differential equation, the first step is to find the integrating factor $\mu(x)$

**

**

To find $\mu(x)$, we first need to calculate $\int P(x)dx$

**

**

So the integrating factor $\mu(x)$ is

**

**

Now, multiply all the terms in the differential equation by the integrating factor $\mu(x)$ and check if we can simplify

**

**

We can recognize that the left side of the differential equation consists of the derivative of the product of $\mu(x)\cdot y(x)$

**

**

Integrate both sides of the differential equation with respect to $dx$

**

**

Simplify the left side of the differential equation

**

**

Solve the integral $\int xdx$ and replace the result in the differential equation

**

**

Find the explicit solution to the differential equation. We need to isolate the variable $y$
