$y < \frac{1}{2} x - 2$ , $y > - 2 x - 1$

Step 1

Simplify the first inequality.

Step 1.1

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

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

Step 1.2

Combine $\frac{1}{2}$ and $x$ .

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

Step 1.3

Add $2$ to both sides of the inequality.

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

Step 1.4

Multiply both sides by $2$ .

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

Step 2.1

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

$x > 2 y + 4$ and $- 2 x - 1 < y$

Step 2.2

Add $1$ to both sides of the inequality.

$x > 2 y + 4$ and $- 2 x < y + 1$

Step 2.3

Divide each term in $- 2 x < y + 1$ by $- 2$ and simplify.

Step 2.3.1

Divide each term in $- 2 x < y + 1$ by $- 2$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$x > 2 y + 4$ and $\frac{- 2 x}{- 2} > \frac{y}{- 2} + \frac{1}{- 2}$

Step 2.3.2

Simplify the left side.
