|x|<6

OpenStudy (charlotte123):

x < 6 x < -6

OpenStudy (solomonzelman):

yes, and when you check, don't plug in 6 or -6, plug in something that is a little less.

OpenStudy (anonymous):

what about, |x - 1|>4

OpenStudy (charlotte123):

@SolomonZelman Yes!

OpenStudy (anonymous):

Wrong x < 6 and x > -6 or another way of putting it -6 < x < 6

OpenStudy (anonymous):

x -1 > 4 OR x - 1 < -4 x > 5 OR x < -3

OpenStudy (anonymous):

how would you solve, |2x + 6|<16 :)

OpenStudy (charlotte123):

2x + 6 < 16 2x + 6 < -16 - 6 - 6 - 6 - 6 2x/2 10/2 2x/2 -22/2 x < 5 x > -11
