Question

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

Answer 1

Answer:

x<-3

This means numbers less than -3 are solutions.

Step-by-step explanation:

9(2x+1)<9x-18  is the given inequality.

Distributive property applied:

18x+9<9x-18    

Subtracting 9x on both sides:

9x+9<      -18

Subtracting 9 on both sides:

9x    <      -27

Dividing both sides by 9:

 x     <        -3

The solution is x<-3 which means anything less than -3 is a solution.

Answer 2

Answer:

x < -3

Step-by-step explanation:

using the distributive property, distribute 9(2x +1) so it's 18x + 9, subtract 9x from 18x, subtract 9 from -18, divide both sides by 9, x < -3
