Question

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

A: -4
B: -3
C: -2
D: -1

Answer 1

The answer would be-4

Explanation:

Here,

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

or, 18x+9 < 9x-18

or, 18x-9x<-18-9

or, 9x<-27

or, x= -27/9

Therefore, the value of x is -4.

Hope it helps...

Answer 2

A:-4

Explanation:

If you simplify 9(2x+1)<9x-18 you will get 9x<-27. That will mean x<-3 and the only answer for something less than -3 is -4.
