Solve for d -11-2d>=1

$- 11 - 2 d \geq 1$

Step 1

Move all terms not containing $d$ to the right side of the inequality.

Add $11$ to both sides of the inequality.

$- 2 d \geq 1 + 11$

Add $1$ and $11$ .

$- 2 d \geq 12$

Step 2

Divide each term in $- 2 d \geq 12$ by $- 2$ and simplify.

Divide each term in $- 2 d \geq 12$ by $- 2$ . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$\frac{- 2 d}{- 2} \leq \frac{12}{- 2}$

Simplify the left side.

Cancel the common factor of $- 2$ .

Cancel the common factor.

$\frac{- 2 d}{- 2} \leq \frac{12}{- 2}$

Divide $d$ by $1$ .

$d \leq \frac{12}{- 2}$

Simplify the right side.

Divide $12$ by $- 2$ .

$d \leq - 6$

Step 3

The result can be shown in multiple forms.

Inequality Form:

$d \leq - 6$

Interval Notation:

$(- \infty, - 6]$
