abs%286y-2%29%2B4%3C22 Start with the given inequality


abs%286y-2%29%3C18 Subtract 4 from both sides.


Break up the absolute value (remember, if you have abs%28x%29%3C+a, then x+%3E+-a and x+%3C+a)

6y-2+%3E+-18 and 6y-2+%3C+18 Break up the absolute value inequality using the given rule


-18+%3C+6y-2+%3C+18 Combine the two inequalities to get a compound inequality



-16+%3C+6y+%3C+20 Add 2 to all sides


-8%2F3+%3C+y+%3C+10%2F3 Divide all sides by 6 to isolate y



----------------------------------------------------

Answer:

So our answer is

-8%2F3+%3C+y+%3C+10%2F3



which looks like this in interval notation





if you wanted to graph the solution set, you would get
