Question

solve for d.
d + 2 < 8 or d + 5 ≥ 13
write your answer as a compound inequality with integers.

Explanation:

Step1: Isolate d in first inequality

Subtract 2 from both sides:
$d + 2 - 2 < 8 - 2$
$d < 6$

Step2: Isolate d in second inequality

Subtract 5 from both sides:
$d + 5 - 5 \geq 13 - 5$
$d \geq 8$

Answer:

$d < 6$ or $d \geq 8$
