If you are referring to the e.g. that starts at 12min02sec, my answer is x=6. If you substitute this to the LHS of the question, it is (6-2)/2 - 6/8 = (4/2) - 6/8 = 5/4. RHS of the question is (x-1)/4, if you substitute x=6 into it, it becomes (6-1)/4 = 5/4. So when x=6 (my answer), LHS equals RHS of the question. Hope this helps.
If you are referring to example that starts at around 7min28sec, my answer is x=18. If you substitute the value back to the question, LHS is (18-2)/2 - 1 = (16/2)-1 = 8-1 = 7, which equals to RHS of the question
每日用打機浪費嘅時間睇一兩次你嘅教學片上堂唔識嘅數學都明白晒😊
叻仔👍
狗仔好得意！
这个教学方式不错 不会令别人觉得无聊 老子喜欢owo
學數都不想睡了
😊 太好了

15:13 為什麼要把4放進括號裡*2 ？是因為要拆括號嗎？我還是小學，不會如何拆括號
是不明白為何 4(x-2) = 4x - 4*2 = 4x - 8
@@user-freetutorial 對
@@劉承希 這是括弧的特性，如果想容易明白多一些，可以看看以下：
3(2+1) = 3(3) = 9
如果我將3乘進括弧裏
3(2+1) = 3(2) + 3(1) = 6+3 = 9

上次的IQ題？
4:12 有上次IQ題的答案
請問你可唔可以出多條片教好像1y+2y=3y+2 的調位教學和example
拍咗一條片關於代數，睇吓幫唔幫到你 ua-cam.com/video/wcSbLk2-HRE/v-deo.html
@@user-freetutorial 謝謝你 你幇了我個大忙👍👍👍
唔好客氣 😊
為什麼19:28. 8(x-1)會變成8x-8??
8 乘 (x-1) 等於 (8乘x) 減 (8乘1)
即是 8x - 8
以上可解答你的問題嗎？
老師教得好好，但係我哋黃棣柵今次不考🥲🥲🥲
學咗先，將來會有用

可否教吓如何用fx-50FH2計算機來計一元一次方程pls
我冇呢部計數機係手，但係另一個UA-camr 嘅片有介紹點樣用fx-50FH2 計聯合二元一次方程，你可以用作參考 😊

The R.H.S also need to times 8
Hi Fred, please tell me which example, such as by specifying the start time of the example, so that I can review the answer. Thanks

Why challenging questions (1) K is x+2 不是大一歲嗎？why not X+1 ? 2是這樣來的？
😢。。。。。。。。。😢
K 大 E 一歲
E 大 C 一歲
所以 K 大 C 兩歲
其实你可以出直播
可以考慮 😊
我忘了，如何找L C M
Lee Man 我為你拍左條片，有時間就睇吓啦 ua-cam.com/video/8C0a0hn9Mts/v-deo.html
你好似挑戰題第一題計錯左
第幾分鐘？
K是21，E是22，C是23
K (KumaMon) 年紀最大，23歲。 C(Cookie Monster)年紀最細， 21歲
若還有不明白的地方，可以在這裏問我
The answer in e.g. 1was wrong, the answer is 7

教得好好啊!
我不記得怎樣估算？？?
