Step 1.1

Subtract $x$ from both sides of the inequality.

$- 2 y > 2 - x$

Step 1.2

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

Step 1.2.1

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

$\frac{- 2 y}{- 2} < \frac{2}{- 2} + \frac{- x}{- 2}$

Step 1.2.2

Simplify the left side.

Step 1.2.2.1.1

Cancel the common factor.

$\frac{- 2 y}{- 2} < \frac{2}{- 2} + \frac{- x}{- 2}$

Step 1.2.2.1.2

Divide $y$ by $1$ .

$y < \frac{2}{- 2} + \frac{- x}{- 2}$

Step 1.2.3

Step 1.2.3.1.1

Divide $2$ by $- 2$ .

$y < - 1 + \frac{- x}{- 2}$

Step 1.2.3.1.2

Dividing two negative values results in a positive value.

$y < - 1 + \frac{x}{2}$

Step 2

Find the intersection of $y < - 1 + \frac{x}{2}$ and $y < - 1 + \frac{x}{2}$ .

$y < N o (Min i m u m)$
