Question 892208: Hi, I was wondering if you could please help me with an absolute value question please? I did the math and got -5 and 5 and it is an "or" line but they both equal the equation. The problem is |3x| > 15. I did this:
3x>15 Or 3x>-15
3x/3> 15/3 3x/3>-15/3
x>5 x> -5
The problem is that they both equal 15 & the problem is >15 Found 3 solutions by josgarithmetic, lwsshak3, MathTherapy:Answer by josgarithmetic(39617) (Show Source):
An absolute value will always be positive or zero; never negative.
IF THEN .
IF THEN -----multiplied by -1 on both sides must cause reversal of inequality direction
Draw a number line and label with -5, 0, and 5, so you can see clearly. Graph and . You will see that the solution which satisfies BOTH conditions is or, the open interval between -5 and +5.

3x>15 Or 3x>-15
3x/3> 15/3 3x/3>-15/3
x>5 x> -5
The problem is that they both equal 15 & the problem is >15
|3x| > 15
Thus, 3x > 15 OR 3x < - 15
You should get: OR
