The absolute value of 3 times a number x is greater than 33.

|3x| > 33

3x > 33

x > 11

what about -11

**Anonymous**, Tuesday, February 7, 2012 at 5:40amgood question.

|x| = x if x>=0

So, your answer of 11 correctly solves

3x > 33

But, |x| = -x if x < 0

so, the other condition is

-3x > 33

x < -11

So, if x is farther than 11 units from 0, in either direction, 3x is farther than 33 units away from 0.
