Question 280251: Hello,
I am trying to solve this equation:
|3.5z| > |7|
(absolute value of 3.5z is greater than absolute value of 7)
I know how to solve when absolute value is on the left hand side, but what do you do when both sides have an absolute value?
Thanks,
Angie

--------------------------
That |7| is 7 since there is no variable involved.
---
|3.5z| > 7
3.5z > 7 or 3.5z < -7
z > 2 or z < -2
--------------------------
