KSP:

Spent the whole morning and came out with this. Let me try it tonight.


500
|---X---||-Y-| --> X + Y = 500
|-Y-|300 --> X - Y = 300

The 2 units of Y is equal to 500 - 300 = 200. So each Y is 100.

Then Y + 300 = X ==> 400

Laughter's DD gave us the right modeling for this question. Use different lenght of rectangle to stand for X and Y.

Hi folks,


That book that i mentioned is \"Teaching to Mastery Mathematics, Bar Modeling, A Problem-solving Tool\" by Yeap Ban Har, from Marshall Cavendish Education. I bought this book from popular.
