Step 1.1

Combine $x$ and $\frac{3}{5}$ .

$\int \frac{x \cdot 3}{5} d x$

Step 1.2

Move $3$ to the left of $x$ .

$\int \frac{3 x}{5} d x$

Step 2

Since $\frac{3}{5}$ is constant with respect to $x$ , move $\frac{3}{5}$ out of the integral.

$\frac{3}{5} \int x d x$

Step 3

By the Power Rule, the integral of $x$ with respect to $x$ is $\frac{1}{2} x^{2}$ .

$\frac{3}{5} (\frac{1}{2} x^{2} + C)$
