Question

What value of x is in the solution set of the inequality 9(2x + 1) < 9x – 18?

–4
–3
–2
–1

Answer 1

- 4

Explanation:

9(2x + 1) < 9x - 18 ( divide both sides by 9 )

2x + 1 < x - 2 ( subtract x from both sides )

x + 1 < - 2 ( subtract 1 from both sides )

x < - 3

the only value from the list tat is less than - 3 is - 4
