My dad threw me the challenge. Super random la he. I did in within 5 minutes but not with a page of complicated algebra and doesn't look like what a p6 student will do.
The Question.
My working. Filled the page of the small jotter book. Workings jumping everywhere.
Anyone can solve it with a simpler method? Pls teach me. LOL.
