Question

Solve for s. 2|s| = 18

A. s = –9
B. only s = 9
C. only s = –18 or s = 18
D. s = –9 or s = 9

Answer 1

Explanation:

Answer 2

2|s| = 18

First, divide both sides by 2. / Your problem should look like: |s| =
`(18)/(2)`
Second, simplify
`(18)/(2)` 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
