*I is used for absolute value notation
The Attempt at a Solution
a) Ix+3I > 0 then Ix+3I= x+3
b) Ix+3I < 0 then Ix+3I= -(x+3)
when solved this would yield to;
a) x>-3 and x>-1
b) x<-5 and x<-3
from my general reasoning i think the answer should be x>-1 and x<-5. Why are the solutions x>-3 and x<-3 omitted? Is it because the other two include a broader range?
thanks for your help.
