Question 979762
the 5) part is correct.

|2m+3| < 13

2m+3<13  you can always just take off the brackets, and that will give you one solution
2m<10 ; m<5

2m+3 > -13
2m> -16
m>-8

(-8,5) is the interval.

if m is -9, you get |-15|< 13, and that is not true.

if m is 0 it works, if m is 6 it does not work.
