Question

determinati toate numerele intregi x care verifica relatia:a) |2x-6|=0 b) |3x -12|=0 c) |4x+20|= -6 d)|3x-27|=0.Va rog urgent imi trebuie pana la ora 10:00 plsss

Answer 1

a) |2x-6|=0
-2x+6=0
-2x=-6
x=-6/-2
x=3
b) |3x-12|=0
-3x+12=0
-3x=-12
x=-12/-3
x=4
c) |4x+20|=-6
-4x-20=-6
-4x=-6+20
-4x=14
x=14/4
x=7/2
d)|3x-27|=0
-3x+27=0
-3x=-27
x=-27/-3
x=9
