Question

solve for s.
2s + 15 < 9 or 2s + 9 > 17
write your answer as a compound inequality with integers.

Explanation:

Step1: Solve first inequality

Subtract 15 from both sides:
$2s + 15 - 15 < 9 - 15$
$2s < -6$
Divide by 2:
$s < \frac{-6}{2}$
$s < -3$

Step2: Solve second inequality

Subtract 9 from both sides:
$2s + 9 - 9 > 17 - 9$
$2s > 8$
Divide by 2:
$s > \frac{8}{2}$
$s > 4$

Answer:

$s < -3$ or $s > 4$
