I realized quite a handful of **O-Level Maths** students aren't strong in fundamentals of Algebra. One of them is solving linear inequality.

I've prepared a 4 minutes video to share with you 2 approaches. One of them requires you to remember the changing of inequality sign when you multiply or divide a negative number to the unknown (or variable). The other approach doesn't require any new knowledge.

You choose your preferred way and stick to it for all linear inequality questions.

Love to hear from you which approach you use. Leave me your comments.
