Step 2.1.1.1

Combine $x$ and $\frac{9}{5}$ .

$- \frac{x \cdot 9}{5} + \frac{3}{5} y = 2$

Step 2.1.1.2

Move $9$ to the left of $x$ .

$- \frac{9 \cdot x}{5} + \frac{3}{5} y = 2$

Step 2.1.1.3

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

$- \frac{9 x}{5} + \frac{3 y}{5} = 2$

Step 2.2

Add $\frac{9 x}{5}$ to both sides of the equation.

$\frac{3 y}{5} = 2 + \frac{9 x}{5}$

Step 2.3

Multiply both sides of the equation by $\frac{5}{3}$ .

$\frac{5}{3} \cdot \frac{3 y}{5} = \frac{5}{3} (2 + \frac{9 x}{5})$

Step 2.4
