Step 1

Simplify the first inequality.

Step 1.1

Rewrite so $x$ is on the left side of the inequality.

$- x - 3 < y$ and $y > 2 x$

Step 1.2

Add $3$ to both sides of the inequality.

$- x < y + 3$ and $y > 2 x$

Step 1.3

Divide each term in $- x < y + 3$ by $- 1$ and simplify.

Step 1.3.1

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

$\frac{- x}{- 1} > \frac{y}{- 1} + \frac{3}{- 1}$ and $y > 2 x$

Step 1.3.2

Simplify the left side.

Step 1.3.2.1

Dividing two negative values results in a positive value.

$\frac{x}{1} > \frac{y}{- 1} + \frac{3}{- 1}$ and $y > 2 x$

Step 1.3.2.2

Divide $x$ by $1$ .

$x > \frac{y}{- 1} + \frac{3}{- 1}$ and $y > 2 x$

Step 1.3.3

Simplify the right side.

Step 1.3.3.1.1

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

$x > - 1 \cdot y + \frac{3}{- 1}$ and $y > 2 x$

Step 1.3.3.1.2

Rewrite $- 1 \cdot y$ as $- y$ .

$x > - y + \frac{3}{- 1}$ and $y > 2 x$

Step 1.3.3.1.3

Divide $3$ by $- 1$ .

$x > - y - 3$ and $y > 2 x$

Step 2.1

Rewrite so $x$ is on the left side of the inequality.

$x > - y - 3$ and $2 x < y$

Step 2.2

Divide each term in $2 x < y$ by $2$ and simplify.

Step 2.2.1

Divide each term in $2 x < y$ by $2$ .

$x > - y - 3$ and $\frac{2 x}{2} < \frac{y}{2}$

Step 2.2.2

Simplify the left side.

Step 2.2.2.1.1

Cancel the common factor.

$x > - y - 3$ and $\frac{2 x}{2} < \frac{y}{2}$

Step 2.2.2.1.2

Divide $x$ by $1$ .

$x > - y - 3$ and $x < \frac{y}{2}$
