$d\leq -7$

Step-by-step explanation:

Move all terms containing to the left side of the inequality.

Add -19d to both sides of the inequality.

$-38d-57+19d\geq 76$

Add and 19d.

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

Add to both sides of the inequality.

$-19d\geq 76+57$

Add and 57.

$-19d\geq 133$

Divide each term by and simplify.

Divide each term in $-19d\geq 133$ by . When multiplying or dividing both sides of an inequality by a negative value, flip the direction of the inequality sign.

$\frac{-19d}{-19} \leq \frac{133}{-19}$

Cancel the common factor

$\leq \frac{133}{-19}$

Divide 133 by -19.

$d\leq -7$

The result can be shown in multiple forms.

Inequality Form:

$d\leq -7$

Interval Notation:

$(- { \infty} ,-7]$
