You probably just had a typo by leaving out the - in front of 10/3 in your second last line
it should say
-10/3<x<8/3
Why are you writing the endpoints as an ordered pair (-10/3,8/3)?
Are "they" showing you to do that?
solve and write in interval notation
|6x+2|<18
-18<6x+2<18
10/3<x<8/3
(-10/3,8/3)
