Question 158598: #31. |2x-1|/|3|= 5
**The absolute value is all around 2x-1/3
I tried multiplying everything by 3 to get rid of the fraction and got:
|6x-3| = 15 and |6x-3| = -15
I solved the problem like that and got {-2, 3}
The answer shown at the end of the textbook is {-7,8}, but I don't know how they got that answer.
