Step 2.1

Divide each term in $- y > - 3 - 3 x$ by $- 1$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$\frac{- y}{- 1} < \frac{- 3}{- 1} + \frac{- 3 x}{- 1}$

Step 2.2

Simplify the left side.

Step 2.2.1

Dividing two negative values results in a positive value.

$\frac{y}{1} < \frac{- 3}{- 1} + \frac{- 3 x}{- 1}$

Step 2.2.2

Divide $y$ by $1$ .

$y < \frac{- 3}{- 1} + \frac{- 3 x}{- 1}$

Step 2.3

Simplify the right side.

Step 2.3.1.1

Divide $- 3$ by $- 1$ .

$y < 3 + \frac{- 3 x}{- 1}$

Step 2.3.1.2

Move the negative one from the denominator of $\frac{- 3 x}{- 1}$ .

$y < 3 - 1 \cdot (- 3 x)$

Step 2.3.1.3

Rewrite $- 1 \cdot (- 3 x)$ as $- (- 3 x)$ .

$y < 3 - (- 3 x)$

Step 2.3.1.4

Multiply $- 3$ by $- 1$ .

$y < 3 + 3 x$
