Identify the solution set of |2x + 5| - 1 < 6 and describe the graph in a complete sentence.

OpenStudy (anonymous):

First, get the |2x+5| part by itself.

OpenStudy (anonymous):

how?

OpenStudy (anonymous):

Well, what part of that equation is making it NOT by itself? How would you move that to the other side?

OpenStudy (anonymous):

add 1?

OpenStudy (anonymous):

Boom. Nailed it.

OpenStudy (anonymous):

Add 1 to both sides, which gets you |2x+5| < 7

OpenStudy (anonymous):

okay i got that

OpenStudy (anonymous):

Cool, once you have the absolute value part by itself, you can break it into two inequalities. |blah blah| < N blah blah < N AND blah blah > -N
