Could someone help with this? I think I know the answer and how to do these type of problems. I just want to make sure.

|4x + 12| = 16

when we have a modulus it removes the negative value right ?
OpenStudy (heschamsaleh):
so we use the answer one time postive and the other negative
|4x + 12| = 16
first
4x+12=16
4x=16-12
4x=4
x=1
OpenStudy (heschamsaleh):
secondly
4x+12=-16
4x=-16-12
4x=-28
x=-28/4
x=-7
OpenStudy (heschamsaleh):
got it bro :D ?
Arcadiouse (arcadiouse):
but the 16 wasn't negative?

Oh okay, so everytime we have a problem like |4x + 12| = 16, we do one time positive and the other negative? @heschamsaleh
OpenStudy (heschamsaleh):
yes my dear friend
Arcadiouse (arcadiouse):
Thanks! I really appreciate it.
OpenStudy (heschamsaleh):
