Question

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

Answer 1

Answer:
x < -3

Step-by-step explanation:

step 1 - distribute

9(2x + 1) < 9x - 18
18x + 9 < 9x - 18

step 2 - subtract nine x from both sides of the expression

18x + 9 < 9x - 18
18x - 9x + 9 < 9x - 9x - 18
9x + 9 < -18

step 3 - subtract nine from both sides of the expression

9x + 9 < -18
9x + 9 - 9 < -18 - 9
9x < -27

step 4 - divide both sides of the expression by nine

9x < -27
9x/9 < -27/9
x < -3

Therefore, x < -3.

Answer 2

x < -3

Step-by-step explanation:

9(2x + 1) < 9x – 18

18x +9 < 9x – 18

-9x -9x

9x +9 < – 18

-9 -9

9x < – 27

÷9 ÷9

x < -3
