Mod of any number is its positive value. For example, mod of 4 is 4 and mod of -4 is 4

You're welcome :) You can solve it now?

OpenStudy (anonymous):

I understand why but I don't know how to solve it .. lol

OpenStudy (anonymous):

Oh okay mod of 3b = 9 b = 9/3 = 3 OR and mod of -3b = 9 b = 9/(-3) = -3 So b = 3 or -3

OpenStudy (anonymous):

Tell me if you get it, or I'll try to make it clearer...
