2|s| = 18
First, divide both sides by 2. / Your problem should look like: |s| = [tex] \frac{18}{2} [/tex]
Second, simplify [tex] \frac{18}{2} [/tex] to 9. / Your problem should look like: |s| = 9
Third, break down the problem into these 2 equations. / s = 9 and -s = 9
Fourth, solve the 1st equation: s = 9.
Fifth, solve the 2nd equation: s = -9
Sixth, collect your solutions. / Your problem should look like: s = ±9
Answer: D) s = -9 and s = 9
