OpenStudy (anonymous):
|5x-2| (greater than or equal to 8

|5x – 2| >= 8
Two scenarios:
First one: Just drop the bars.
Second one: Drop the bars, switch the inequality sign, and make the 8 negative.
OpenStudy (anonymous):

OpenStudy (anonymous):
okay sweet what do i do next?
OpenStudy (anonymous):
add 2 to both sides
and after that divide by 5
OpenStudy (anonymous):
5x<=-10 would this be right after adding 2 to both sides?
