This is a more challenging simultaneous equation question for Form 4 SPM Add Mathematics.

Why not you try it first before watching the video? Here’s the question

Here’s the video tutorial to answer this question. (Do the question first, then only watch this video. Don’t be lazy! You can only do well in Add Math if you do them yourself.)

Note : – If you can understand the solution after watching this video, then I advise that you do the question again after watching. Make sure you get the correct answer this time.

Note : If you find this difficult, then try Video 1 and Video 2 first. They are questions with simpler simultaneous equations
