#### Answer

$d \leq -2.5$

#### Work Step by Step

Add $3$ to each side of the equation to move constants to the right side of the equation:
$2d \geq 4d + 5$
Subtract $4d$ from each side of the equation:
$-2d \geq 5$
Divide each side by $-2$. Remember that when we divide by a negative number, we need to reverse the sign:
$d \leq -2.5$
