Step 3.1.2.2.1

Move the leading negative in $- \frac{2 x}{9}$ into the numerator.

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

Step 3.1.2.2.2

Cancel the common factor.

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

Step 3.1.2.2.3

Rewrite the expression.

$9 y = - 2 x + 9 \cdot 2$

Step 3.1.2.3

Multiply $9$ by $2$ .

$9 y = - 2 x + 18$

Step 4

Move all terms containing variables to the left side of the equation.
