Well done! You are right.
But we don’t teach elementary school children how to form equations. It’s cognitively too abstract for them.
Here’s how the kiddos are supposed to solve this.
Of course, if a precocious kid were to solve this problem using your method, he would be awarded full marks.
I wonder what was the success rate...
Just watched the video... this is like solving equations without calling them equations... not sure if this way is easier or more intuitive :)

for the record, my work started with the two bottom lines, and then the two lines above.
I don't explain my work, but a math teacher like you will recognize what's going on.
this is simply what came to me. maybe we should teach elementary children how to form equations.
