i need help solving inequities with absolute value

OpenStudy (anonymous):

Sure

OpenStudy (anonymous):

\[3\left| 2x-1 \right|=21\]

OpenStudy (anonymous):

whats the first stewp?

OpenStudy (mertsj):

1. Divide both sides by 3

OpenStudy (anonymous):

what about the bars?

OpenStudy (anonymous):

You have to isolate them first so like @Mertsj said, divide by 3 first (it's like solving for 3x=18 to get x first oy have to divide by 3)

OpenStudy (mertsj):

Did you divide both sides by 3?

OpenStudy (mertsj):

One step at a time.

OpenStudy (anonymous):

\[\left| 2x-1 \right|=7\]

OpenStudy (anonymous):

no its -7

OpenStudy (anonymous):

You were correct it''s 7

OpenStudy (anonymous):

wait thats not the correct problem

OpenStudy (mertsj):

21/3=7 NOT -7

OpenStudy (anonymous):

You have an absolute value equation and that means that their's a positive and a negative value for this equation because \[\Large |-3|=3~~~~and~~~~~|3|=3\]

OpenStudy (nincompoop):

it says "inequalities" of the absolute value. But the problem has "=" 3|2x−1|=21|dw:1374459500522:dw|
