Question

solve for w.
9 > -9 - w

Explanation:

Step1: Add 9 to both sides

$9 + 9> - 9 - w+9$
$18>-w$

Step2: Multiply both sides by -1 and reverse the inequality sign

When multiplying an inequality by a negative number, the direction of the inequality sign changes. So, $18\times(- 1)<(-w)\times(-1)$
$-18 < w$

Answer:

$w > - 18$
