When you have an absolute value equation in which you have the absolute value of an expression is less than a number, you change it like this:
|expression| < number
negative of the number < expression < number
In your case this wuill be:
-5 < 2x - 1 < 5
OpenStudy (anonymous):
that's the answer ?
OpenStudy (konradzuse):
2x -1< 5 and 2x -1< -5

I just need the answer, or easy steps am almost finished I only need 5 more answers to be done
OpenStudy (mathstudent55):
-5 < 2x - 1 < 5
Add 1 to all three parts:
-5 + 1 < 2x < 5 + 1
-4 < 2x < 6
Divide all three parts by 2
-2 < x < 3
