<u>Given</u>:
The given inequality is 
We need to determine the solution of the inequality in interval notation.
<u>Solution of the inequality:</u>
The solution of the inequality can be determined by simplifying the inequality.
Thus, we have,


Subtracting both sides by 3, we get;

Subtracting both sides by 2u, we have;

Dividing both sides by 4, we get;

Writing it in interval notation, we get;

Thus, the solution of the inequality is
