Given:
The compound inequality is

To find:
The solution for the given compound inequality in interval notation.
Solution:
We have,

Subtracting 6 from each side, we get


Divide each side by 3.


Here, 1 is not included in the solution set and 3 is included in the solution set.
Therefore, the solution in interval notation is (1,3].
Answer:
Only x=-2 is an extraneous solution is the answer
Step-by-step explanation:
You need to add what the lines are if you want them to be analysed for you^^
