inequilty help please

OpenStudy (anonymous):

\[-2\left| 5-x \right|<-6\]

OpenStudy (anonymous):

i have x>-3/5 and x>3/5

OpenStudy (anonymous):

thanks prime

OpenStudy (mathstudent55):

First, divide both sides by -2.

OpenStudy (anonymous):

ive obviously done the work, i have my solution there! is it correct?

OpenStudy (mathstudent55):

I can only tell if I solve it. Give me a minute.

OpenStudy (anonymous):

i have x>-3/5 and x>3/5

OpenStudy (mathstudent55):

-2|5 - x| < -6 |5 - x| > 3 5 - x < -3 or 5 - x > 3 -x < -8 or -x > -2 x > 8 or x < 2

OpenStudy (anonymous):

how did you do this 5 - x < -3 or 5 - x > 3 -x < -8 or -x > -2 how is dividing 5 from both sides -8? -3/5=-8?

OpenStudy (mathstudent55):

This is how you solve this type of absolute value inequality: When you have an inequality of the form |X| > a where X is an expression in \(x\) and \(a\) is a number, the solution is x < -a or x > a

OpenStudy (mathstudent55):

We can dio this problem one step at a time together.
